Airline reviews

Air India Express operates as a separate airline, so it says. Air India Express is a subsidiary of Air India and is part of the Tata Group, which acquired a 100% stake in the airline. (https://www.tata.com/business/air-india-express). Yet Air India express is not a member of Star Alliance, so Star Alliance gold members do not receive the benefits they would had they traveled on a mainline Air India flight. Even though it's a subsidiary of Air India, which is a Star Alliance airline. Very frustrating.

When landing in Hyderabad, the pilot made a hard landing. Everyone in the plane were shocked. The captain landed the plane hard and felt as if we were going to be thrown out from our seats. It was surprising the captain didn't apologize or make an announcement about. Again a surprise no crew acknowledge this. This was an odd experience!

I appreciated a meal on the shorter flight. It was slightly delayed with no announcement but I was able to determine what was happening.

I don't think there were entertainment options (short flight) - which is why I gave the 'ok' sign. Didn't make a diff in my flight experience either way, however

Really old air craft, broken seats and tray tables. Entertainment screens don’t work. Charging ports didn’t work.

Poor, pilot flew as if he was in hurry and had to coverup for wasted time

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

The planes did not have charging jacks for phones or lap tops and there are no monitors for movies. On the flight from Delhi to Hyderabad I was the last person in First asked for a meal choice and only one meal was available so I had no choice.

Flight got delayed by 3 hours but no compensation or anything

Booked thru Kayak -> Indian Eagle. One leg of flight was cancelled after check-in (CCU to Del). Rebooked thru Indian Eagle cancelled again and rebooked. Cancelled once more now scheduled for CCU-BOM-JFK on Jan 18th. Let's see if this gets cancelled again. Would not book any tickets thru India Eagle - they are just a ticketing intermediate and for questions they ask you to call Air India. They "request" booking but apparently I got bumped after ticket was confirmed. Much better to book directly with Air India - avoid Kayak and Indian Eagle. I paid for Travel insurance can't see it any more on Indian Eagle site to contact.
