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

Insights shared by verified travellers who flew the route from Istanbul to London 
EmreFlew with Turkish AirlinesIST-LHRSept 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.

Recommend packing plenty of snacks and games or download plenty of films and music in your device. Staff excellent. Clean flight. On time.

Both of my flights had issues with their time slot with air traffic control, so they left over an hour late and the flight back to London was delayed by over an hour. Please provide more clarity about baggage requirements on booking sites, your website and within the app. I had to pay for extra bags at the airport when departing London, because they didn’t specify that your carry on bag can only be a backpack and not a trolley, my trolley bag fit the size requirements of the backpack but still I was made to pay

The crew at Check-in was very helpful. It’s was appreciate.

It’s a budget airline. You get what you pay for. They insisted on getting us out of the gate and into our slot on time. They got us to the destination safely. Aircraft was clean and well maintained. What more could we want

Half an hour delay. Squeezed into a small Departure Lounge with very few seats. Noisy flight with screaming unruly kids. Loud IPads and Phones. Heaven!

Were delayed in the airport for 5 hours with no explanation. Flight kept getting delayed by an hour at a time and wizz air staff were no where to be found

The flight was delayed 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.

It's a budget airline. Great for short flight. Smooth landing.
