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

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

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

Poor boarding with incorrect gate numbers. Poor service they told me to throw away brand new water bottles. Poor immigration officers most likely American who hates Muslims. Poor service in the plane with no Urdu language sign posted anywhere. Horrible seats with no comfort at all they think people traveling in economy are animals. Slow food and water services. Slow baggage arrival.

Very delayed and uncomfortable seats. Nothing written in Urdu for Pakistanis. Tons of Pakistanis use the airline they should ensure the airline is accommodating them properly.

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.

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.
