The long-haul flights are operated on the airline’s Airbus A321neo aircraft, and the lie-flat business class seats are arranged in a staggered 2-2, 1-1 configuration.

You can play around with dates on Google Flights and then book directly through TAP Air Portugal or through an online travel agency (OTA) like Expedia.

• Class: Business
• Routes: Boston (BOS) to London (LGW)

Best Ways to Book

You’ll find scattered availability on TAP Air Portugal between the fall of 2023 and the spring of 2024.

Plug in your preferred dates into Google Flights, and then book. If you book directly with the airline, you may end up paying $200 more than what’s being quoted on OTAs like Expedia, so keep that in mind before booking.
