Jet2 have chosen to paint their latest 737-800 in a livery similar to the one worn by the two leased Allegiant 757s. Is this the beginning of a new livery to be worn by some aircraft promoting Jet2holidays?
It could be. Reason I think this is because the actual Allegiant Air livery/logo is a slightly different style to this especially the sun on the tail...
In my opinion though it looks quite messy and definately doesn't suit the current jet2 or jet2holidays style writing or colours. It may start messing with their brand image to the different arms of the company to passengers point of view too.
