You’ll find the cheapest deals on TAP Air Portugal between Boston (BOS) and London Gatwick (LGW). All deals include a layover in Portugal, usually in Lisbon (LIS).

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)
  • Dates: November 2023 to March 2024
  • Rates: As low as $2,095 round-trip

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.

Either way, make sure you pay with a card that rewards you for travel purchases. Some of our favorites are below:

Final Thoughts

This is a deal we’ve seen in the past, as TAP Air Portugal regularly has cheap flights to Europe. Still, fall and winter are popular times to visit London, so finding a lie-flat business class deal from the U.S. is always good news. If you’re interested, make sure to book ASAP before the deals are gone!
