Hi, thanks for the comments. Answers to the questions are;
1) Yes, flight was in Economy
2) I think the visa cost 3 Kuwait Dirhams (About 7 British Pounds / 11 US Dollar), and was well worth it
3) I changed my return flight back for several reasons, one was I didn't particularly find the airline safe (just a feeling, it probably is safe), and because of the IFE and for convenience. I'd paid for the ticket myself, however work paid for my Etihad ticket to Europe so in effect it didn't cost it.
Many thanks.
