England is reopening to fully vaccinated travelers from the U.S. beginning Aug. 2, United Airlines is making it easier for business and leisure customers to jet across the pond with the addition of flights to London. In August, United will have six daily flights between the U.S. and London, including a second daily flight from Washington, D.C. and increasing service from Houston to daily. United looks forward to resuming additional London service in the coming months as well as launching new nonstop service between Boston and London. Customers traveling to England must be fully vaccinated in the U.S. with vaccines that have been approved by the FDA and must take a test before departure as well as a PCR test within the first two days of arrival. Passengers vaccinated in the U.S. will also need to complete a passenger locator form prior to traveling to England and provide proof of U.S. residency. United flies to more European destinations than any other U.S. carrier, and is welcoming back customers on more than 30 daily flights to 16 destinations in Europe this summer. The carrier has expanded its service to Europe including new routes to Dubrovnik, Croatia; Reykjavik, Iceland and Athens, Greece.
