I think one of the ways Jet2 is so successful is advertising.
Paris was announced Monday, by Wednesday, I saw at least 6 buses with Paris £24 on the side of them, and a big advertisment in the local T&A.
They have billboards everywhere, advertisment on the side of many Leeds and Bradford buses, and Even in Belfast, it’s full of adverts for Jet2.
I think you need such advertising to get anywhere, and Jet2 are doing a cracking jjob.
