Flights from Istanbul to Heathrow: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Istanbul to Heathrow 
EmreFlew with Turkish AirlinesSep 2024
Do not book the flights to Heathrow as they are star allience joint flights there are a lot of issues with the check-in and transfer documents are not checked in Turkey so there is a huge wait time problem during the border control due to this. It takes approximately 15 minutes for someone to go through checks because of this and if you are back at the que after the flight this issue costs you 2 hours wait time at the airport.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Outdated business class on this aircraft, no flat bed, and even minimal recline. Couldn’t sleep at all. Laggy and outdated entertainment system. Food sub standard.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

I was sitting almost in the back, the seats are very tight and there’s no legroom, it’s uncomfortable for a long distance

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

I hate to have pay for my first luggage 165$ when I did my search on Kayak with 2 luggages .I don't plan to use kayak in the future and go with Turkish airlines directly

It was great except my luggage was C severely damaged over i picked it up off the carousel in London. . A suit case that had been used once does no longer have the use of the extendable arm as it’s broken

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

Amazing trip! No delays, no broken or lost luggage, and amazing food.

Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

Love the A380 - loads of room. Headphone socket on my seat didn’t work. Sounds like a trivial issue? Well when flying long-haul the in-flight entertainment is what keeps you going so when it doesn’t work it’s a disaster. Pay attention to the details please BA. Spoiled what was otherwise an excellent flight with the usual brilliant crew.

Crew were fantastic can’t fault them at all. Couldn’t do enough for us

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?

I was told to be there to check in three hours before my flight and the counter only opened up two hours before. Apparently that is standard. So that was an hour I could have spent walking around Larnaca that was wasted. But besides that it was great

horrible! after going through hell and back to get a flight home after my flights got cancelled I also had a delay of 2hrs stuck inside the plane because of some technological problem.

I enjoyed the comfort of Premium Economy. The Purser on London-Nairobi was a little testy, snappish in his tone. I understand stressed, tired, etc but his tone in addressing passengers I found wanting.

Outdated from start to finish. Good was inedible, choice was very poor. They don’t seem to care

Very good crew. The seating in economy plus was excellent, and I slept most of the way. The diabetic meal that I requested was almost tasteless--about a 2 on a ten-point scale.--so I ate little. And why bother serving dinner to fliers at midnight?! I had eaten a meal at the airport six hours earlier. A good breakfast would be better.

British Airways Flight 525 from Florence to London on July 29th 2025 was the worse flight I have ever been on. The flight was excessively delayed with poor communication from airline as to the reason for delay. We were notified of need for an unscheduled stop in Pisa after boarding due to weather which was limiting ability to fuel up to the capacity needed for the flight to London. Though we understand and appreciate the safety concern, on quick web search we later learned this was a recurrent problem. We were subsequently kicked off our connecting flight out of London to Port land, Oregon (also on British Airways) though that flight was also delayed (we were told we would not be able to make it in time, but ironically the amount of time it took for them to rebook us would have been more than sufficient to make the connection). We then had to stay overnight in London at a very mediocre hotel, had to take a flight out on a different carrier which involved a stop at LAX (not a direct flight to our home city which we had paid extra for the convenience). Half of our bags did not arrive in LA and we had to transfer the bags ourselves from the international terminal to terminal 6, only to have most of this luggage that made it from London to LAX not arrive in Portland. They bags were eventually found but took over 60 hours for delivery. The entire trip home which was suppose to be 13 hours took over 40.
