Over all good experience. Cabin crew should have been more attentive and the food quality should improve.

Luggage jandling sucks. I arrived in BLR india on 15th and luggage was delivered today 19th. I came for a business trip everything got screwed up. Poor communication. APP kept saying mishandles in BLR. It never reached BLR. I had air tag which showed luggage was in Germany. I could not reach anybody other than the airpprt people. They had no clue and asked me to call etihad. In India etihad number wasnt working.i had to call US number and that person was the only person who seemed to help. They kept me in dark. No communication or email till i spoke to the person in US.i have flown many airlines but never had this experience. For me this was first and will be last in etihad. Very bad.

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

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

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Only 1 time food and drinks together was offered, for total 5 hours duration drinks and snacks was never offered. For some people food choice was not available, only veg was available. No entertainment option was there. Crew members were mostly back of the flight asking each other for KitKat and chips to share between them.

Crew were very polite and quicker in service. Excellent cooling, comfortable seats and tasty food served

Entertainment did not work from flight from Abu Dhabi to Kolkata. Emirates has a much better flight in that sector.

Short travel duration. However, I had placed meal preference while booking my air ticket but was given vegetarian meal on board. Food was okay. Not so great. Didn't like Spanish eggplant, cold chickpeas salad. No hot soup was available. Everything cold cold only.

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.
