On schedule, courteous, and efficient. Old aircraft with not so nice lavatories.

Food was excellent.. better if there are more movies selection.

Had picked seats while booking tickets but airlines reshuffled the seats without informing and we were again left with the worst possible seats on the return journey. terrible experience.

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

The food wasn’t good at all. I skipped meals .

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

Food option Hindu veg to Hindu non veg request was unheard

No seperate security check for business class passengers and average lounge, open air, so not properly air conditioned

Paid for the seat 17D. I found that that seat has no lean back facilities

Flight was short but turbulent giving uneasy feeling :( ; although views were mesmerising ;)

Flight boarding experience with journey was smooth; can describe it as a less to minimal turbulent flight!

I paid 675£ for LHR-BOM-BKK (return flight). They charged so much money but provide very less food/drinks as compared to another airlines. Never ever fly with Indigo.

Just fly from point a to b. rest holds zero stars. And with zero competition, what do you expcect

Flight was delayed 110 mins.. Crew on Ground or in Air had no regrets.. No apologies... Very poor boarding process... Awful food and beverage choice.

Flight was delayed and due to this we almost miss the connection flight

Although we took the XL seats with more width, we found that you do not have a seat in front to stow your personal item, nor can you stretch your legs. This is not the best option for a comfortable seat. Boarding was timely but disorganized without any row based entry.

Flight was delayed and also lots of mosquitoes on the flight

Flight was delayed by 1 hour 20 minutes. Boarding experience was pathetic, even arrival got delayed due to lack of ground staffs.
