Terrible airline... Originally, the flight was canceled and didn't receive a notification, had to learn from their twitter account... Rebooking was a huge pain... Every other airline like American and United did eventually fly a day later... The flight had a layover, no other airline needed one... India is such a weak nation globally, this airline has no leverage to negotiate good airspace... Flight left late, again no notifications as to why at the airport. On the plane, wifi is spotty, chargers don't work... The only saving grace used to be good food. Even that has gone down the drain. Just the worst!

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.

Never ever travel with Air India is a very conscious promise made to myself. Poor customer service , irresponsible staff, pathetic operations and bad planes. Overall -0/10. Planes had mosquitoes in it.. i am still thinking what international standards of hygiene are they even following????. Operations team has no quality standards. They can route you anywhere on any plane inspite of a confirmed ticket and a web checkin… without your consent. Go for AirIndia if you love challenges and roller coasters and safety, time and hygiene is never your priority.

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

Inflight Services are poor compared to other airlines. They do not offer even water during 15 hr flight. Food is little in portion and I had food poisoning after last meal ( rajma chawal)

Boarding at Mumbai airport was terrible, the staff had no idea how to handle it. It was chaos - and led to a delay

My seats that I paid for were changed last minute and I had to sit in uncomfortable chairs

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .
