It’s a business class ticket but they didn’t give a lounge access

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

excellent, the staff was kind and the boarding process was with no issues or hassle

More leg space than other flights, but *maybe* narrower seats

My baggage was not boarded and is still missing. I was only carring one piece of luggage and that is misplaced now I am stuck at mumbai without luggage. I had an onward journey from here

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

I was charged $604 for a bag that weighed 17 kg. I was given three different prices until they landed on the most expensive one and didn't budge a penny. It's ironic and a bit enraging because the total cost of my ticket was $468. I've traveled the world and never experienced these kind of prices for only one piece of checked luggage.

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

Etihad charged me for 2 check in bags. On Kayak search results price was showing 2 check in bags were included. Kayak need to reimburse me for these additional charges and metal agony and distress. Thanks.

Same problem place in the middle so small Im 1,85 m so not good 👍
