American Airlines and British Airways have round-trip flights from Dallas (DFW) to London (LHR) for $548-$577, NONSTOP or with a connection. October to March. Departures on Tuesday, Wednesday, and Sunday. Flight may operate as a Finnair code-share.
Note: Carry-on bag is allowed for free. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.
Note: We feel that this deal is inferior to the $351 Delta/Virgin sale that we posted last month, but it’s a good price for Nonstop flights if you’re building loyalty with Oneworld.
