Amazing! Big line at Check in was diminished in 10 minutes. Boarding was quick and efficient. Service and food great. Only minor point: seats could be a little broader and for me being small, something to put your feet on during the flight would be great.

Amazing! Big line at Check in was diminished in 10 minutes. Boarding was quick and efficient. Service and food great. Only minor point: seats could be a little broader and for me being small, something to put your feet on during the flight would be great.

Except for spending an extra day in Istanbul due to late departure from Athens on Saturday and missing the connection flight TK0044 to Cape Town and again arriving 45 min late on Monday in Cape Town, it was all good.

The best food I’ve ever been served on an airplane. The security at the gate was frustrating as was the heavy editing of the films and television shows offered.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

It was an old airline with the old configuration of business class seats. Not really what we signed up for for the longest leg of the trip. Disappointing.

flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work

Very bad overall. The comfort level was undeniably uncomfortable. The in-flight entertainment was no good because my screen froze and “wasn’t able to reset”. The staff were rude and non-helpful. Instead of offering me an upgrade for all inconveniences for the ticket, and seat I paid extra for, I was offered a downgraded seat all the way at the back of the aircraft. The flight was delayed for so long, making the experience at the layover airport that much more unpleasant.

Food wasn’t nice and doesn’t have halal option

Light and recline did not work on my seat. Very uncomfortable and could not read in the dark

great. I could have used a bottle of water or two instead of having to ask everytime. great service. very comfortable

Terrible, We experienced massive delays and then couldn’t book a hotel through the link provided, nothing was available. We then went to the airport the next day and experienced further delays, almost no communication was given. We had dinner at lunchtime and breakfast at midnight. We then landed in Jhb at 1am and had to book another hotel as our flight to durban was at 8am. The experience was painful and very expensive.

Flight was cancelled at the last minute with no explanation. No viable alternative offered and zero customer service support. Totally useless.

Experience with British Airways was hopeless and the response from ground staff after flight cancellation was hopeless

3/4 bags delayed and 1/4 damaged at the other end. Flight was freezing

this was a good experience from on time boarding and take off to early arrival. Comfortable seats became empty seat next to me.

Cancelled flight, limited information and chaotic rebooking and accommodation provision. Apathetic crew who were more interested in taking about their layover plans than remembering passengers orders and actually bringing them (after 3 reminders). To top it off, priority baggage checked in at The Wing (LHR’s first class checkin) was delivered last to the baggage belt.

The crew were good. The flight was on time. The entertainment choice was ok. But the food was bad, tasted and texture were awful.

After boarding we were waiting in the plane for more than one hour to take off without AC with very high temperature inside

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.

Only for BA because we had to get to Edinburgh at a certain time. Baggage lost, late boarding with only one person checking, again, our passports and boarding passes until the despatch controller had to step in to get us away. Will never fly BA again.
