Hey everyone, I was wondering if I could get some of you more experienced travellers advice on what happenned with my etihad flights over the summer.

So travelling from london l took 4 etihad flights:
1) LHR to AUH
2) AUH to KUL
3) BKK to AUH
4) AUH to LHR

Flights 1 and 2 were connecting flights and there was no planned stopover. However,there was a delay leaving Heathrow of over an hour meaning we reached Abu dhabi over an hour late and disembarked the plan 30 mins before the connecting flight was scheduled to leave. Once we disembarked we were gathered together and held for 10 minutes before being told we would not be allowed onto the flight to Kuala Lumpur as they cannot delay the flight. It was just after midnight and we were given rooms at the airport hotel. The connecting flight staff were appalling but that's not what this post is about. We were fairly given seats on the next flight to Kuala Lumpur which was the following morning at 10am. This flight was delayed by over an hour again which was rather humorous seeing as the reason they gave us as to why we couldn't board our initial flight was because "flights to kuala lumpur cannot be delayed". So we arrived at our destination 12 hours later than we had booked.

The return journey from Bangkok to Abu dhabi was also delayed though I admit this wasn't exactly etihad's fault. A passenger decided they didn't want to fly which resulted in them and their luggage in cargo being removed. This resulted in a delay of over 2.5 hours. Luckily we had booked a couple nights in Abu dhabi so didn't miss the connecting flight to london as many others did.
Our final flight from Abu dhabi to London was also delayed by over an hour.

I did submit a complaint to Etihad customer relations and they did up their offer of compensation to 20,000 air miles each. Is this fair? As a student I really don't have much used for air miles so I was wondering what you guys would do in this situation.

Sorry for the long post and thanks in advance for any replies
