Jet2 crew bases
Skipness,
Should Alicante not be on that list? They do tend to have a 733 stationed there, I understood that some crew were based there also?
The backup ac has been able to position to airports around the network quickly and hence keep the operation running smoothly. I've seen examples of where the plane was deployed to Pisa and Tenerife before from there for rescue missions. Potentially has upsides in terms of minimising costs from extensive delays while keeping things on track..
