HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

Direct flight to BALI was good and convenient. Improvement suggestions - provide complimentary water

50 minutes delay on boarding,but overall delay time almost 2 hours on arrival.

I specifically searched for flight with checkin bags. Airfare assist website still sold tickets without check in bags and I had to pay 3 times more for my bad. Worst experience ever with untrained staff and haphazard boarding

As a frequent flyer, I was impressed with the smooth take off.

No frills means no frills... I just got on the plane and flew. That's all. Nothing more and nothing less. Or I did buy some water, they took cash only! LOL

First the flight delayed 1 hour ND then when we suppose to landing the pilot decided not to land at the chiang Mai Airport but the chiang rai airport

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

The flight was delayed by 3 hours, causing me to miss my connecting international flight. I then had to wait in the airport 18 hours for the next flight. The reason for the delay was a computer issue, not something outside of their control like weather. To add insult to injury, instead of trying to expedite the flight to make up for lost time, they ran a carry-on baggage check to verify every bag onboard belonged to someone on the plane, which took another 20 minutes.

झूठा है इंडिगो फ्लाइट में मील दिया नहीं जब शिकायत किया तो बोला आपको मिल चुका है

It took a lot of time to declare that the flight gonna be cancelled ☹️ very disappointed.

They denied my meal which was included in ticket and also damaged my bag completely and broke the wheel and still not accepting their fault

As budget airline everything was good. Except that - boarding process can be more organised. Then if entertainment systems are not operational. Its better to keep them switch off.

Flight cancelled after 4+ hour delay. Indigo created a nightmare scenario and showed the most callus attitude towards the passengers I will refer to them was IndiNoGo!

Very nice and pleasant. Boarding was quick and the crew were responsive

The flight on the 8.10was canceld so i had to by tickt on anather airline As the low say i will need a full refand of the mony i paid you for this flight! Thenk you Dan richental

No snacks meal or drinks for 9hr flight, no entertainment options. Crew appeared tired, irritable. It's apparently a budget airline, they make sure it feels that way.

Un peu déçu par le vol, c’est la première fois que je prend un vol de 6h ou les boissons et la nourriture sont payantes et pas inclus dans le vol. Peut être que c’est propre à la compagnie mais ça m’a surprise. Le fait qu’il n’y est pas d’écran pour pouvoir passer le temps était aussi un point négatif. Cependant le personnel était très agréable.

First time of flying with Air Asia and great choice

Don't even offer water on a 5 and half hours flight. Its laughable one have to rent a blanket.

No free water. Water cost money in a currency that I didn’t have.

Pay for food on an almost 6 hour flight. Very tight space, I had to show my boarding pass for the food I paid and the blanket set. I had an online boarding pass, that didn’t work, I had to take out the printed boarding pass out of the overhead locker whilst my neighbour was eating, as I was sitting in a Center seat. The staff was very friendly and got my bag out but it didn’t make sense. As the online boarding pass was enough for the blanket set. But not for the food. Just to make a check on the piece of paper. I had a warm free meal on an one hour flight from BKK to Samui with Bangkok airways. So airasia just tries to save money where they can.

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

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 flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

Flight has no entertainment. Crew doesn't care atall. Horrible service and never going to take Air india and will spread their Horrible service.

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

Undisputed leader in sky for Indians. Very good crew right from ground to mid sky. Very sumptuous meals twice

I reached the check in counter 1 hour before take off and was denied boarding because the luggage could no longer be transferred to the flight. I was aback when throughout the world(including India) for a domestic flight, you need to report 1 hour before boarding. Then on top of that i was made to buy a brand new ticket. I had paid $350 for a business ticket between delhi and mumbai and then was made to buy another economy ticket for $100, No concessions/discounts were made for the airline's own inefficiency! The reservation counter was also extremely rude and unapologetic about making me pay a second time. For such a mediocre airline, there seems to be zero focus on providing good service to their customers and providing a pleasant experience.

Worst staff from Vienna. one of the server was very rude and annoying as she thinks she owns the airlines

Overall it was good. But air planes should be upgraded.
