I got back a week ago from Holguin, Cuba with Thomson's premium. No amenity packs, but a blanket and neck pillow on the seat both journey's. I thought the service was still worth the money, for the legroom alone. We had plentiful drinks services both ways and hubby has to drink lots of water (for health reasons) when flying and they were only too happy to fetch it, or he'd just go to the galley and ask. The food was not to my liking outbound, but hubby and friends both enjoyed theirs, and inbound it was surprisingly good!!

Hubby did have a headphone issue, but it was soon sorted. I enjoyed the IFE outbound, but was too tired to be bothered inbound, but my friend watched two good films. We had a newspaper both ways I think, and a pack with OK, Star and New inbound. Also had a water bottle in the seat inbound.
The premium crew going out were friendly and helpful and coming back the head steward? (or whatever they're called these days) really had a great sense of humour. He had everyone laughing before we'd even got in the air, as did the captain on one occasion. I can honestly say all the crew we had dealings with were helpful and cheerful enough. The seats are not the comfiest but we sit on our blankets and they were better.
Our friends luggage did come off last both ways, but she says it always does, irrespective of where they go or who they fly with!!

None of us would book a longhaul without the premium seats, and hubby certainly couldn't manage with 33" for 10 hrs. I know it is quite an added extra on top of the holiday cost, but we always factor it in when picking our holidays.
