Thanks Powerjet1
Interesting though--i have just tried again and again it is only offering me October.
I have tried Flights to other destinations(Tenerife) without problems from LTN and MAN but not TLV for some reason.
I am currently in New Zealand , wondering if its because i am here and not in the UK trying to book.Shouldnt be a problem should it !!
Site keeps saying " The Flights you have selected are during a busy time or no Flights are Available at this time"---For all months !!
Even more bizarre is the timetable section doesnt even show the flights.
Will e-mail Tui and find out whats happening.
Thanks for your help
