Hi flying mermaid.......excellent trip report.....pity the airline website isnt clear. I did manage to get through to Etihad this morning. I felt a bit sheepish asking such an odd question but they said they certainly DO provide sleeper suits (italian designed)as well as an amazing Salvatore Ferragamo satchel amenities kit for first class on the A340-600 flights ex Melbourne. Managed to find an obscure link to the kit if anyone is interested complete with a few pics.
I'm flying in a few weeks and will post a report as i go
