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.

I paid $110 for a seat located at the start of a section and therefor would not have a chair in front of it, but this is not what I received. The floor plan was different from when I booked my ticket. This is very disappointing and my money needs to be returned.

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.

Very comfortable flight. I appreciate the announcements were also in English.

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

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

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.

Entertainment systems did not work at all And the seats are the worse on this 787-8 aircraft. Normally I get good sleep on long flights but this time I only slept 2 hours out of the 8+.

The web check in doesn’t work. Had to wait 10 minutes on the counter for them to figure out boarding. I understand AI Express doesn’t have a practice to offer food to everyone in the business class. The flight attendant asks for name (not sure why she doesn’t know it especially with only 8 passengers in the business class) to figure out whether or not they should serve food. KAYAK should sell AI Express tickets separately, not as part of AI. Neither the experience close to AI, the Maharaja points also don’t get awarded despite Express being part of AI.
