I am trying to find short haul flights to book with TUI for S19 to/from Greece, that are operated with 767 and 787 but the problem is that dummy bookings on their site do not give you beforehand info about the a/c operated..(unless it's op by Norwegian which we know is 737). You have to pay first and then on check-in oyou find out..which is weird because when i tried to book it gave me the option to pre-book a seat but seating plan would not open,it just said pre-seating selected..Is there a way to be able to know what a/c will be operated on certain flights? I dont wanna book for a 767 and get a 738..although i wouldn't complain about a 757..Oh and seat-guru says their 757s seat 235 but Tui site says 221..So which is it?
