Flights from Dallas to the United Kingdom: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Dallas to the United Kingdom 
PamFlew with American Airlines-Mar 2026
Book premium economy. The extra comfort is worth it.
TaniaFlew with British Airways-Apr 2026
Heathrow airport has become one of the worst airports. Way too massive, like Amsterdam's, way too much walking & navigating. Better have 3 hours for connections and prepare to walk for HALF OF THAT time. LHR was 1 of the best airports 60 yrs ago. Don't expect it to stay same but now its a nightmare. For older folks I suggest using a less massive airport in UK and for American Airlines to do same.

If you can't check in online do it by phone, don't do it at the airport because the system sucks!

Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

All good- I love BA and the professionalism of the crew and pilots.

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Had a nice flight to London on BA will fly with them again in the future

The plane was warm and stuffy. The crew was friendly but got 2 orders wrong. I asked for sparkling water and wine with dinner and got neither. I asked for black coffee with breakfast and got coffee with cream. Service was so slow on my side of the plane they ran out of 2 of the 3 desserts at dinner and I was in row 12.

My first time in business class The in flt staff was outstanding in every aspect of service, the food was amazing, the business seat space made the 11 hour journey easy peazy

Spent over $20k on for business class tickets from DFW. They used a very old Boeing 777 with old Business class cabin which was unclean and stained seats. On a route they normally operate the modern Boeing 787. The cabin heat was set to hot for 11 hours. On the IST LHE route the business class experience got even worse. They operate an even older Airbus A330 where trip was falling apart, seat recline did not operate and the whole experience left us hugely disappointed. Next time we likely will shift to better quality product which stands up to their hype. Turkish need to relook at their fleet plans and not use their worst assets of perceived week markets such as Pakistan.

The flight from Houston to Chicago was delayed, causing us to miss our connecting flight to Madrid, losing our Rental Car booking in Bologna taking alternative travel routes to get to our initial destination in Pizza by the 15th. We got the notification of the delay as we were traveling the 3 1/2 hours from Corpus Christi, Texas to Houston Texas for the initial flight. The delays hauling luggage all over Milan‘s Central train station to catch trains to get to Pizza the same day resulting us arriving in Pizza at 2 AM leaving us no time to rest as there was a 9 o’clock checkout time the next morning. The first 72 hours of the trip with nothing but headache, a knee injury from the excessive walking and a delayed car rental replacement, which ended up costing significantly more.

Amazing! One of the best kept secrets in air travel!

It was a pleasant experience. In flight entertainment could have been better

I have travelled many times on Turkish, but they always board at least 30-40 minutes past the stated time. If informed properly, passengers can choose to spend more time in the .lounge instead of standing around by the gate waiting to board. The new lounge at DFW was a big disappointment. The aircraft itself was a shock. In the past I have flown this sector with regular business class seating configuration of 1-2-1, The 2-3-2 seating is very disappointing after paying such high prices for tickets. The DFW to Istanbul segment was slightly better, but the Istanbul to Delhi segment was no better than premium economy. I will try to travel more on airlines which give business class passengers more value for their money.

Bad experience; they are not good anymore. They charge too much for luggage seat are so uncomfortable, Flight delays which may miss your next flight, they don’t care if you miss the flight or not. Zero customer services for front desk representatives Istanbul's airport I’m not using this airline any more.

Good overall flight. Excellent crew. Food options could be improved.

I was flying with Turkish Airlines from Tashkent to Dallas and from Dallas to Tashkent. In both directions the flights were late. I missed my connecting flight from Istanbul to Dallas in Istanbul airport because of that. That led to a no show case with a rental company in Dallas and I lost 460 US dollars. On the way from Dallas to Tashkent with a layover in Istanbul the plane was also late and I almost missed my connecting flight to Tashkent. Then my bag did not arrive with the same plane and only on the next morning flight from Istanbul. I was about to leave Tashkent the same day to Astana in Kazakhstan and then from there for work in Saudi Arabia. Luckily I had an excess in time before the next flight and I manage to get my bag back. Otherwise I would have missed 3 flights automatically because I couldn't travel for work without my bag and all valuables in it. So, overall, very bad experience with Turkish Airlines. Will never use these airlines again.

The 787 economy was a disaster for long haul. The space was too little compared to 777 or 747. Also the extremely low tray table behind the seat made any dining effort a nightmare. However, the movies were up to date, and the food taste was good, despite of terrible serving process caused by small space.

This trip on American was the WORST I have ever experienced. The plan was LATE taking off from Tucson due to mechanical issues. It caused me to arrive late in Dallas, so I tried to move flights so I would not miss my dinner meeting. First attempt, that flight was delayed, Second attempt, that flight was also delayed. Got back on original flight, the mechanical issue was NOT fixed, so we de-planed and had to find the new gate. Overall, was which was 4 hours delayed and missed the dinner meeting. Friday return, flight from Orlando was on time and landed early. Then the next flight was delayed due to crew coming in late, and them waiting on other passengers. After 90 minutes of delay, we boarded, and then were informed the Fist Officer could not fly due to time constraints. At 12:15 AM we were offered a hotel for a 4:20 boarding flight. Not happening. DFW was COLD and no place to sleep. Plane delayed again to 6:50, but was late taking off AGAIN. Finally landed in Tucson at around 8AM. Should be refunded 75% of the ticket costs due to negligence, nothing more.

American eagle and American Airlines are bad, cancelations, delays and no customer service

Three terminal changes in DFW and once again a flight that was delayed. On time departures are rare with American. Not loving my experience lately. I fly every week.

We had bad delays and waited for hours on end, we did receive a 12 dollar coupon to use in the airport though. Oh wait, we got that on the plane so we couldn't even use it. I truly never want to fly American ever again.

Flight DFW > CVG was delayed with late notice. My flight into DFW from CVG (previous) was delayed by multiple hours with very poor communication & advance notice. And having the flight attendants announce the credit card during the flight when I can't opt felt very insulting and cheap. I already paid you for the flight, you shouldn't be able to take my time and attention hostage for further advertising.

It was freezing in the cabin. That's on me to be better prepared in the future.

They delayed my flight 6 hours and gave me $12 for food that I couldn't use it anywhere.

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

A 50 minutes flight that is delayed over 90 minutes kills every connection, thank you American Airlines

We spent two hours on the plane before taking off due to a fault which I would have thought they would have found before boarding so we could have stayed in the airport. Water was in short supply so restricted due to the extra time and so hot. Vegetarian food was awful and wish I hadn’t ordered it and was left starving

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

We departed late but made up most of the time in flight. Our ticket was pure economy, so it wasn’t anything fancy; however, I heard that we arrived in Madrid at the exact same time that First Class passengers arrived! Overall, our experience was similar to what we had on other American Airlines transatlantic flights - good value at a reasonable price. We were even able to get our carry-on baggage onto the plane without needing to gate check it.

The crew were not very personable. The crew did not serve tea or coffee. The bathroom was not kept clean. Two out of the 5 toilets in the cabin weren't working.

I described my experience in the previous window. I didn't realize that there would be another opportunity for this flight. Please look at my response in the previous window.

Boarding was 2 1/2 late no explanation Captain said he did not know why, but he rested at home for an extra couple of hours. Food was edible, Nothing more.

The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

The airline refused to board me because I showed up only 50 minutes prior to departure time, despite the fact that shortly before that, when I arrived at the airport still in time, they changed the terminal and I had to take a bus that took 20 minutes. Keep in mind that for some maintenance error I could not check in online like I usually do. Personnel at the airport was unable to let me in, customer care was beyond useless, the original airline operator (Iberia) was as useless as a toilet paper roll core in time of a wipe and all this uselessness made me waste my ticket, my reservations, my long time parking, food and most of all the joy of being with my family for the new year after working my bottom off even at Christmas. Am I happy? Come and ask me in person!

The food was horrible. The crew skipped over me for drinks(only got food?). I had to wait until everyone else was served drinks in order to receive mine(meal was done). No earphones were given. No free WiFi.

We left our child’s tablet on our seat 12 B on the plane and we can’t get a hold of anyone to try to get help locating the tablet.

we originally had premium economy seats when we booked, but because we were forced to re-book because the first leg of our journey was delayed for several hours, we had to fly economy. Less room, less comfortable.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even

Didn’t fly with them as someone had cancelled my flight

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

They cancelled the flight from Dallas to London and rebooked following day causing a lot of pain

Very bed boarding, there was overbooked and make a lot of problems and noises

The flight was delayed numerous times with inconsistent updates and very ambiguous information. When it was finally cancelled the logistics of handing out vouchers and rebooking was extremely chaotic. Meal vouchers were completely inadequate for the airport restaurants, and not even accepted at some. All-in-all, it was a very disappointing experience.

No luggage at end of flight… no coffee with soggy breakfast flatbread (I think) for breakfast! Stewardess did not seem to care, asked her to take remainder of evening meal trash… she never came back for it. Awkward when trying to get up in confined space and have to get around tray that is down!
