Although I was in economy it made no difference where the staff were concerned they were attentive and pleasant throughout the flight maybe one day I'll get the chance to see if there's a difference in business or 1st class service but in truth for the way I was treated I can only see the menu being an upgrade as the staff don't need upgrading and are indeed the biggest asset on a long journey a credit to the company.
