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.

this was a short flight in business class. I had problem in the Istambul airport - the lounge for Turkish Airlines was too far and we never were able to reach it

this was a short flight in business class. I had problem in the Istambul airport - the lounge for Turkish Airlines was too far and we never were able to reach it

Luggage never made it it’s been 2 days and no proper update

The flight from Istanbul to Karachi was an old plane in which the seats don’t even come close to lying flat. It was uncomfortable - may as well have been economy, and a far cry from Qatar Airways that I’m used to. The food was mediocre and entertainment couldn’t even be used because there was zero privacy like in a normal business class, so it would feel as though everyone is watching the movie with you - which is awkward. I had to put my food tray out as a leg stopper to get into some sort of comfortable position to curl up and sleep, which is ridiculous. Unacceptable given the ticket still has a business class price tag.

My seat number was changed unilaterally after confirmed online checkin from widow to aisle. This applies to the Istanbul-Port louis flight. Seat was also changed for the Antalya-Istanbul flight but this was because of aircraft change, I was informed. That flight was delayed because of a technical problem with the original aircraft.

This is not business class. This is premium economy. Total scam to sell this as business class

Seats too much and for the price we paid eve thought economy we still had to pay $169 to check a ba that’s ridiculous and also my daughter needed water so she can take her medicine we push the boton for the attendant to get us water they never came we push it 3 times no one came and ask what we needed . Am not happy with the service at all I will not fly with TK anymore

Boarding experience was a mess- both to and from Istanbul airport. No one knew anything. They asked everyone to line up according to their sit numbers- it was unbelievable. Business class had a separate line, but it was hard to find- I had to go through all that mess before finding it. Would not recommend

My experience with Turkish Airlines was good. I didn’t get the meal I ordered. So I didn’t have anything to eat which was disappointing.

They can my date of travel and let me standard in Istanbul for three days stop over and only pay for one day in a hotel with only one breakfast for three days.

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

Big queues on arrival at airport despite having already checked in and only needed to drop bags off. Flight delayed which impacted on connecting flight.

The update about flights and the terminal changes information was great.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

Although business class, the seating was really cramped. The food was so so.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

Entertainment did not work from DC to London. Was not able to check in online during my return journey from Mumbai to London. Food was good!
