I would be interested to know how much airlines save by not providing free food & drink on-board their a/c.
On a no-frills flight, it is probably better to bring your own water and sandwiches.
I actually flew one of the longest 'no-frills' flights ever, last summer, in the US. It was Jetblue 85 from SEA to JFK-lasted about 4 and a bit hours-as a non-American, I have nothing but praise for the likes of JB-their A320 was spotless, the seats were quite comfy (grey leather), live-tv was on offer-but most surprising of all, FREE water and cookies were delivered to my seat TWICE!!
That struck me as being a bit 'frills'!! For $100, I wasn't complaining!
Ryanair were reported to be interested in insatalling the JB live-tv system, but it would be pay-for-view, with the dreaded credit-card swipe fitted to the side!
