I was happy that I was able to get a last minute flight but unfortunately my seat was a middle seat. Even with Delta Comfort I wasn't comfortable

I was happy that I was able to get a last minute flight but unfortunately my seat was a middle seat. Even with Delta Comfort I wasn't comfortable

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

Flight was warm for first few hours and quite rough

Seat was extremely hard which made even a short 1 hour 20 minute flight fairly uncomfortable.

Improve boarding- the zone assignment and boarding is always a mess- there is not clear instructions of what is going on at the gate. As a meme bet there is no more selection of a good seats when booking. Only offers middle seats to choose or pay extra. There is not more benefit with Amex no benefits at all.

alike schedule and times it’s very good for me, I will stay wad delta for ever

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

two hour delay and the Delta representative on the PA system was unable to understand

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

Typically great service from Turkish with comfortable seat and amenitie, good food and great attention from staff.

Delicious food, comfortable and clean plane. It's a little cramped in the hall in front of the gate.

Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

The crew on this flight provided exceptional business class service to me.

The staff at the boarding or the rudest uninformative and no English whatsoever they’re very rude as if they are envious of you travelling I don’t understand how could someone would be this rude and this out of touch and cold

You charged me for luggage although the airline does not- you charged me for seat when customers can pick their own seat at checkout in I travel to Europe slot and I will not use kayak again

Requested food options were always finished. Supplied food items were good but of course not the desired choices.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

Very bad experience with turkish airline tk 0001. Very uncomfortable seats and food ran out and crew was not helpful

The airline could improve its business class seats and privacy in line with its competitors.
