It was a pleasant experience. In flight entertainment could have been better

The desk crew at the LAX crew could do better. A girl named Mahesi was very abrasive and unfriendly. She needs a better customer service uproar.

It was peaceful excited We enjoyed it always Turkish peaceful excited

Istanbul to Lahore flight was less than standard for international business class cabins. Seat did not were not flat and it did not operate easily. I had to push buttons hard repeatedly to operate the seat. I was in 5A seat

IAH to Istanbul was outstanding across the board. The flight from Istanbul to Male was good, not great.

the cabin was kept too hot. couldn't sleep as a result

It was an amazing experience. Flight crew's service, hospitality, and the food were phenomenal. I don't think I'd want to try any other airline company after this. I would definitely recommend to friends and family. Thank you Turkish Airlines !

Business Class pods are horrible. If you're petite, you might be able to sleep on the uncomfortable seat and bed. Crew and food are fantastic.

I have travelled many times on Turkish, but they always board at least 30-40 minutes past the stated time. If informed properly, passengers can choose to spend more time in the .lounge instead of standing around by the gate waiting to board. The new lounge at DFW was a big disappointment. The aircraft itself was a shock. In the past I have flown this sector with regular business class seating configuration of 1-2-1, The 2-3-2 seating is very disappointing after paying such high prices for tickets. The DFW to Istanbul segment was slightly better, but the Istanbul to Delhi segment was no better than premium economy. I will try to travel more on airlines which give business class passengers more value for their money.

Good overall. Seat spacing a bit tight between IST and ISB.
