古巴：旅遊政策變更

自 2017 年 6 月 16 日起，受美國司法管轄的旅客，無法再前往古巴進行個人民間交流旅遊。所有乘搭聯合航空往返古巴的旅客，皆必須證明自己符合其中一種授權類型的旅遊資格。請參閱美國財政部古巴旅遊頁面，了解更多關於美國公民前往古巴旅遊的授權類型資訊。

飛往美國國際航班的其他安全措施

除了標準的安檢程序之外，美國國土安全部 (DHS) 要求所有飛往美國的國際航班加強安檢措施，針對大型電子產品、粉末物品、食物、書籍和雜誌等日常物品加強安檢。國運輸安全管理局 (TSA) 網站提供完整清單詳列允許及不允許攜帶的物品。

大型電子產品：旅客攜帶的電子產品尺寸若大於標準智慧型手機，則應事先將這些裝置從保護殼或外包裝拿出來，以進行安全檢查。若您攜帶的保護殼需要螺絲批或其他特殊工具才能移除，建議在抵達機場前就先行移除。

粉末類物質: 建議所有的旅客將粉末狀的物品放入寄艙行李中。部分旅客若於隨身行李與個人物品中攜帶超過標準汽水罐大小（12 液體量盎司或 350 毫升）的粉末類物質，依美國國土安全部規定，可能要進行額外安全檢查。

針對被選中進行更多安全檢查的旅客，若攜帶超過上述容量的粉末類物質，將不允許攜至航班機艙。粉末類物質例子包括咖啡粉、茶、麵粉、糖與香料。某些物品例外，包括嬰兒配方奶粉、醫療必需品粉末以及人體骨灰。

請注意，某些在中央安檢站執行此項安檢的外國政府可能採取更嚴格的措施，包括沒收和丟棄超出允許量的粉末類物質。

抵達時間：美國運輸安全管理局 (TSA) 建議，請至少在國際航班起飛時間三小時前抵達機場，以便預留更多的時間進行安全檢查。 請先行注意機場辦理登機手續時間。

如需更多資訊，請瀏覽國土安全部 (DHS) 網站。如有特定問題，您也可以針透過 Twitter 或 Facebook Messenger 聯繫 @AskTSA，或瀏覽 TSA 客戶服務。

乘搭由美國海關和邊境保護局預先入境審查的航班

若從下列任何一個國際機場飛往美國，我們建議您於預定起飛時間 3 小時前抵達機場。從上述機場起飛的航班將由美國海關暨邊境保護局進行預先清關，因此請預留更多的時間，以便在出發前完成額外的邊境安檢程序。當您飛抵美國時，您將抵達國內客運大樓。

從下列國際機場起飛之前，乘搭已完成美國邊境保護局預先清關聯合航空公司營運的航班：阿魯巴島 (AUA)、百慕大群島(BDA)、都柏林 (DUB)、自由港 (FPO)、拿騷 (NAS)、夏農 (SNN)、愛民頓 (YEG)、哈利法克斯 (YHZ)、渥太華 (YOW)、滿地可 (YUL)、溫哥華 (YVR)、溫尼伯 (YWG)、卡加利 (YYC) 和多倫多皮爾遜 (YYZ)。

電子系統旅遊授權 (ESTA) 批准

旅行授權電子系統 (ESTA) 近期進行部分變更，並且無法立即處理核准。若您未持有美國護照但要求使用 ESTA 服務，我們建議您在預訂行程時申請，且最晚在旅行前 72 小時完成申請。

Chicago O’Hare & New York/Newark: Space capacity and crowd behavior testing

At Chicago O’Hare and New York/Newark, United is testing new technology to learn how to reduce crowding in this space. We use anonymized data from mobile devices, CCTV and/or sensors at select gate areas and United Club locations to monitor the number of people, solely for managing space capacity and crowd behavior.

This data cannot be used to identify individuals. You can also disable your mobile device’s Wi-Fi to further opt out of detection via wireless networks. Please see below for how we use this data.

How we use CCTV feeds for this test

United uses certain technology to process video feeds from CCTV, which detect non-identifying attributes to create and obtain a count of people within a specific area. We do not process, collect or retain any personally identifiable attributes of an individual.

How we use wireless networks for this test

Wi-Fi or Bluetooth capabilities are available within most mobile devices to allow for connectivity and access to the internet and other technologies. These devices broadcast a Wi-Fi or Bluetooth MAC address (12-digit set of characters) assigned by the manufacturer to allow detection by Wi-Fi or BLE sensors.

United uses its wireless network to detect the available MAC addresses broadcasting within specific areas and anonymizes it into an unidentifiable hashed data string which is then used to provide a count of a device present. We then use this anonymized information to help create an understanding of how many people may be within the area.

We do not collect or retain any personally identifiable attributes which may be associated along with the MAC address nor can we reverse-detect a MAC address once it has been anonymized.

You can turn off your device’s Wi-Fi and Bluetooth functions to prevent detection by wireless networks.

U.S. IDs

Due to the coronavirus, if your driver's license or state-issued ID expired on or after March 1, 2020, and you are unable to renew at your state driver’s license agency, you may still use it as acceptable identification at the checkpoint. TSA will accept expired driver’s licenses or state-issued ID a year after expiration or 60 days after the duration of the emergency, whichever is longer.

REAL ID enforcement

Beginning May 7, 2025, you must present a REAL ID-compliant driver’s license, state-issued enhanced driver’s license or other acceptable forms of identification, such as a valid passport or U.S. military ID, to fly within the U.S. Review the complete list of acceptable identification.

If you don’t present an acceptable form of identification you won’t be permitted through the security checkpoint.

Learn more about REAL ID enforcement and frequently asked questions.

Berlin airport change

Beginning November 8, 2020, flights to and from Berlin, Germany, will operate out of Berlin Brandenburg Airport (BER). This will replace Berlin Tegel Airport (TXL) as the primary international airport for Berlin, and all commercial airline operations at Tegel will end after November 7, 2020. For directions and more information about Berlin Brandenburg Airport, visit https://ber.berlin-airport.de/

Chicago O’Hare construction

Beginning May 28, 2020, two of the four pedestrian tunnels connecting Chicago O’Hare Terminal 1 and Terminal 2 to the main parking area and the CTA Blue Line station will be closed for construction. Alternate routes between each location will remain open and will be marked with signs.

Starting March 30, 2021, utility and pavement replacement construction on the lower level arrivals roadway will begin, eliminating about half of the curbside customer pickup area in Terminals 1 and 2. Some of the crosswalks adjacent to the closed areas and the ramp to the recirculation road will also be closed during construction, which is expected to be completed in 2022. As a result, more traffic congestion than usual is expected for travelers arriving at Terminals 1 and 2. To avoid delays, you’re encouraged to add extra time to your travel plans. Short-term parking for passenger pick-up is recommended.

Beginning April 16, 2021, motorists to O’Hare should expect additional traffic congestion due to ongoing construction on the Kennedy Expressway (Interstate 90). Outbound Kennedy motorists must merge sooner to access ramps, including the ramp to Interstate 190 to O’Hare, as a new collector-distributor road is located just after Canfield Avenue, about one mile before the current ramp access. We recommend allowing yourself extra time to arrive at the airport and to plan for alternate routes.

Cincinnati security checkpoint hours

The security checkpoint at the Cincinnati Airport is open from 3:30 a.m. until 9 p.m. daily. Please plan to arrive at the airport prior to 9 p.m. – even if your flight is delayed – to make sure that you have enough time to pass through the security checkpoint before it closes. It will not stay open late to accommodate delayed departures, and you will not be able to board your flight.

Denver construction

If you’re flying out of Denver, we recommend arriving two hours before your scheduled departure time due to construction in the Great Hall of the Main Terminal. This ongoing construction may result in longer check-in times, new construction walls and limited dining and shopping options. Directional signage will be posted throughout the terminal and personnel will be available to answer questions. Please visit the Denver International Airport’s website for more information.

Denver bag drop

Denver International Airport (DEN) offers free bag drop and check-in service at the Transit Center and 75th Avenue to make it convenient for you to travel, baggage-free, from the time you arrive until you board your flight.

• This service is for flights on United within the U.S. Flights to international destinations aren’t eligible for the bag drop service.
• Drop your bags a minimum of 90 minutes before your flight.
• Skip the ticket counter lines by checking your bag and getting your boarding pass.
• This is a free service. Our bag fees still apply and can be paid at all bag drop locations.
• Travelers with lap infants must go to the ticket counter for the child’s boarding pass.

Transit Center bag check: Check your bag at the Transit Center and get your boarding pass before you head up to the terminal and through security.

• Location: Transit Center, Level 1 (below The Westin)
• Hours: 6 a.m. to 6 p.m. (for flights departing as late as midnight)

75th Avenue drive-up bag check: Drive up and check your bag from the comfort of your car before you park. A greeter will remove your bags from your car, check you in for your flight and even print your boarding pass. Then, park in one of the lots or head to the terminal, baggage-free. Upon arriving at the terminal, head directly to security.

• Location: 75th Avenue near the Pikes Peak parking lot
• Directions: Exit Peña Blvd. at 75th Avenue, proceed straight through the Gun Club intersection and follow signs to the Bag Check queue
• Hours: Saturday through Thursday, 4 a.m. to 4 p.m.; Friday, 4 a.m. to 7 p.m.

Haneda airport processing times

Due to airport expansion occurring at Haneda (HND), we recommend checking in online or with the United app and allowing extra time for checking bags and security screening.

Houston Intercontinental construction and closures

Due to ongoing airport construction, passengers may encounter some traffic delays along North and South Terminal Roads and are encouraged to add extra time to their travel plans.

All vehicle traffic from the Terminal C Departures Ramp will be rerouted through the Toll Plaza and exit through the Terminal E Garage onto South Terminal Road. Additionally, the Terminal D/E parking garage is permanently closed, and passengers are asked to park at an alternate terminal, using the subway train (pre-security) or Skyway (post security) to access Terminal E.

We appreciate your patience and remind passengers to pay close attention to all posted construction signs.

Kansas City airport processing times

We recommend that customers departing from Kansas City (MCI) allow extra time for check-in and security screening, especially during morning hours. Airport check-in counters open at 3:30 a.m. and TSA security checkpoints open at 3:45 a.m.

Lafayette, Louisiana airport processing times

We recommend that customers departing from Lafayette (LFT) allow extra time for check-in and security screening. Airport check-in counters open at 3:30 a.m. and TSA security checkpoints open at 3 a.m.

Los Angeles traffic information and taxi/rideshare pickup

Ongoing construction near Los Angeles (LAX) is causing heavy traffic outside the airport. We recommend allowing extra time and arriving at least two hours before your flight.

Taxi and rideshare pickups leaving the airport have been relocated to LAX-it, a new area accessible to travelers by shuttle or a short walk from baggage claim. Learn more at flylax.com/lax-it

Los Cabos, Mexico, airport construction

Due to construction underway at Los Cabos International Airport (SJD), travelers arriving to or departing from Los Cabos should be prepared for longer wait times during check-in or immigration and customs processing. Boarding areas may be more crowded than usual, and boarding announcements may be limited during this time as well.

New York LaGuardia Terminal B updates

With the opening of the new Terminal B Arrivals/Departures Hall at New York LaGuardia on June 13, 2020, it may take up to 20 minutes to walk from the end of the TSA security checkpoint in Terminal B to the gate area. Travelers departing out of Terminal B after this date should plan to arrive at the airport earlier than usual to allow for this additional travel time.

Phoenix terminal change

All our flights depart and arrive from the new Terminal 3 at Phoenix Sky Harbor International Airport (PHX).

San Pedro Sula processing times

Ramón Villeda Morales Airport has limited resources after damage from storms and flooding, so it may take longer than usual to check in since verification is required for all COVID-19 documents. We recommend arriving at least four hours before your scheduled departure time and using immigration and customs precheck at prechequeo.inm.gob.hn/Login

San Juan additional security screenings

The TSA has implemented additional security measures at Luis Muñoz Marín International Airport (SJU) that require all wet or frozen food items to be removed from carry-on baggage and inspected. While food items are permitted in carry-on baggage, travelers departing San Juan are advised to allow extra time at security or to check bags containing wet or frozen food items to expedite the screening process. This policy applies to standard screening lanes but does not affect TSA Pre✓® lanes.

St. Thomas construction

Renovations are underway at Cyril E. King Airport (STT) in St. Thomas. This may lead to longer wait times for check-in and security screening, so we recommend getting to the airport 3 hours before your departure.

Toronto check-in times

Because of increased congestion at the security and customs areas, check-in for all United and United Express flights will be 90 minutes before departure. We recommend you arrive 2.5 hours before your scheduled departure. If your flight departs before noon, you’ll be subject to a new queue system to optimize the flow of customers. After you check in, look for the signs to determine which line you should enter for your flight.

Vail, Colorado, construction

Construction is underway at Eagle County Regional Airport (EGE), resulting in a longer walk between the TSA security screening and gates. We recommend allowing more time for this distance, and require customers to check in 45 minutes before departure if traveling with checked baggage.

Washington Dulles construction

Construction is underway at Washington Dulles (IAD) near the ticket counters. This may lead to longer wait times if you’re checking in or checking bags, so we recommend getting to the airport early.

Washington National construction

Construction at Washington National Airport (DCA) is expected to cause traffic delays on airport roadways, as work crews close lanes in front of Terminal B. Please allow additional travel time to and from the airport. For pickups and drop-offs, please consider using the Terminal Garages since they are located outside the construction zone.
