I flew on IE last week from MBJ and the only things of note that happened was a big bit of plastic fell from (somewhere) over the economy section toilets on take off,the bloke in front of me had his seat headrest come off so he was grinning at me like a maniac,and a lot of the seatback ents did not work...oh and there was the fight over seat allocations.
But seriously I would not knock the 787,it is more comfortable (in economy) than others in the class,much quieter, and I am sure will have a long service.I would be more than happy to use it again.
(just don't ask about IA)!
