Flights from London to Dallas: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from London to Dallas 
Verified travelerFlew with British Airways-Dec 2025
Bring a seat cushion or sit on the pillow/blanket they provide you.
KateFlew with British Airways-Jun 2024
Leave plenty of time for layover in US as the queues for immigration are very long and you are likely to miss your connecting flight
DavidFlew with British Airways-Mar 2024
Don’t fly to Dallas. This isn’t about BA, but DFW was a really bad experience. TSA was horrible- rude, seemingly delighted in just being unhelpful, actually yelling at pax to “come on, get moving!” then asking why we didn’t have (whatever) out. Uhhh, that’d be because I can’t do it while moving, and not moving isn’t an option. Followed sign to TSA Pre, not there, asked agent who just pointed back where we came and said “follow the signs”. “Yes, they pointed here” “just follow the signs.” Multiple gate changes (to other terminals!) requiring multiple train rides. Just unpleasant. Find another connecting airport.
