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 
CharlesFlew with American AirlinesMar 2026
Recommend you finding another airport for a connection. London Heathrow security process is laborious and very tiring.
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.

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

I really would like it if they provided at least some limited free wi-fi.

I had issue with my boarding pass. When I arrived in London Gatwick Airport. My e-ticket wasn't scanning and had to do a lot of back and forth with Air Transit I order to board my flight, which I almost missed as a result of this.

The food and drinks were below the normal standard we expect from Turkish Airlines. On a 4 hour flight we received 1 drinks service and 1 food service, the latter was a cheese omlete, which is well below what we have received in the past, such a shame we always recommend this airline..

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

A fairly standard 2/2 configuration. Boeing 787-9 is modern but the amenities chosen by Turkish for their seats are slightly limited - no in-seat charging, for example. Otherwise, a good flight.

Not sure how they are rated best airline in Europe. If they are the best; then I worry about the overall airline standards of European airlines. Seats were very uncomfortable and almost closer to budget airlines in terms of comfort. A sore bottom after a long haul flight ruins your holiday at the start. Check in process was okay. Staff/crew was good - interactions ranged from pleasant to borderline rude (depending on the particular individual).

Check-in was a mess, transfer flights were sepersted so no one could sit with their company. Some tickets were closed to online check-in without notice hand luggage allowances were not checked so oberhead bins were already full halfway through boarding.

The flight was delayed by 1.5 hours without much explanation and they ran out of complimentary bag for inflight comfort. Would like to know if i can can get compensation

You can understand why Turkish Airlines are rated so highly; the whole experience was really good indeed. Aircraft itself was spacious, comfortable, and very well appointed. The crew were great, friendly and helpful. All round a great service and good value. Istanbul airport is also a remarkable place. Highly recommended.

Was very bad the cancel the flight after when we arrived to London

They lost my baggage and still waiting an update when I can receive it

American Airlines is the worst airline to fly. you can’t get on an earlier flight if you don’t have ‘status’, they cancel their flights with no warning, and they lie about why their flights are delayed so they don’t have to pay for meals or hotels. They lost me as a customer after this trip. I’ll be flying Delta or Untied from now on.

The checkin process is always horrendous with this airline. They never have enough people working the desk or people assisting in the lines. Rude and unbothered. I never pick British Airways- I always get swapped in via American Airlines and may need to stop using American Airlines as well. No entertainment in flight. And they seem more concerned about selling food and drinks then they are about customer comfort

Terrible service. Stewardess behavior horrible. No sense of customer service. Seats were small, in general very bad experience which is not the case for me on other international flights via BA

TIRED OLD plane. Seat cushion is completely old and NOT cushion at all; after an hour of flying butt hurts. Boarding is a complete disaster. No one respects the boarding groups, and the BA boarding crew care less about boarding groups or Tier status. What is the point of spending all this money on Business Class tickets when no one respects the boarding system? It took 90 minutes since we landed to get our luggage. 20 minutes to show on the screen which belt we are supposed to go to and another 1 hour to get our luggage - not the kind of service you will expect from BA at LHR

My ticket was cancelled unannounced and I was left stranded in the air port

We were told they needed to take some luggage off the plane and it would take 15 min. It took over an hour and no communication from the captain or crew. We were delayed about 2 hours in full.

Apart from missing my flight because of another British Airway plane parking issues and had to wait 7 hours, i'd say all was just ok

I booked 2 tickets together and they separated our seats. A few months before the flight I got a call asking if I want to pay $100 each flight to choose my seat since I won’t get the option but that wasn’t true and i’ve never done seat selection over the phone, very weird. They do offer free seat changes when you check in but there was nothing available. I assume this is because people who book directly with the airline get to choose their seats when they buy the ticket. Will not be booking through kayak next time and will book directly with the airline so we can sit together.
