Difficult to say what I liked, cabin crew very miserable, looked like they were sick of the job and it was their 50th flight if the day, long wait between drinks and food was somewhat very budget. We did travel in economy but with such a long flight you'd expect this type of service with Ryanair for a two/three hour flight to benidorm, not 8 hours over the Altantic.. entertainment was limited with films and difficult to hear even with headphones on. I think the pilot spoke once and I couldn't hear him over the noise in the cabin. I'd say to say you get what you pay for but my opinion I've flown with a much better airlines. Sorry...you dud ask :(
