That may well be the case but EasyJet have already announced some new routes for 2019 but if they do eventually add Palma from SOU with a based aircraft from Palma or a W pattern from another base it may we'll be down to scheduling and fleet utilisation before EasyJet can confirm the ''rumours''!
I would like to know where this so called rumour actually originated from as I've read nothing on the internet other than what's been mentioned on these forums but none the less I hope that it does come to fruition.
