Jet2 are mainly based at Leeds/Bradford and Newcastle so my logical head says they wouldn't create another base between the 2.
However somebody asked Ben Houchen about it a few weeks ago and he said watch this space.so now I'm not so sure.
Jet2 are having maintenance work done on new aircraft by Willis who are based at Teesside. Three aircraft in total but two are yet to have the paintjob done yet.
