I did not have WiFi on the flight in business class. This was a problem on a long 15 hour flight. I had important work to do and was unable to do it. This resulted in loss of productivity .

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.

Verified traveller, Jul 2026

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.

6.0 Okay

Narayanan, Jun 2026

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!
