IndiGo is low cost and therefore no frills, but is always a pleasant experience. No mood lighting and fancy features but clean aircraft, professional crew and absolute value for money.

IndiGo is low cost and therefore no frills, but is always a pleasant experience. No mood lighting and fancy features but clean aircraft, professional crew and absolute value for money.

Very hard seats. No food service, even though price is not competitive.

Very hard seats for long flights. No food even on International flight. Won't fly Indigo again if I can help it.

Terrible experience at IST airport due to mismanagement by ground and wheelchair staff.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good. They should have at least one crew member who speaks the local language, for flights like these.

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.

Not professional and didn’t know about double seat even when I paid for it and have a confirmation. Lack of comms between teams.

deboarding is very poor after landing it took around 45 minutes to come out.

My baggage bag got broken and only 3000 voucher was given for compensation

Crew members forgot to serve sandwiches after serving the coffee. Worst was the handling of bag. One of wheel was Broken making it useless. Though a complaint was registered and assured of compensation voucher equal to part cost of the new bag.
