I want to book with Vueling VY7475 flight on the 1st of September. however, its previous record isn't promising, its flight history here shows that all its flights have been canceled last year and didn't fly since, but their website says the flight on the 1st of September is scheduled. All other flight options I have are 3 times higher the price!
Should I book with them? and How long before the scheduled flight, the airline informs its clients that the flight is cancelled?
