Yes a rebrand to Vueling

according to wiki (The most reliable source ha) They have 35 aircraft on order. And from what I gather IAG still have options for 45 A320neo's. Which I guess will be used to replace the Aer Lingus Short Haul fleet. But I'm sure 15/20 could be transferred to Vueling/BA Gatwick.

Although saying that BA and Gatwick are a confusing one! They invest heavily, then let it go to waste. Then invest again, invested in new North terminal area and now being moved to the South Terminal.
Almost like Lufthansa and Dusseldorf, short haul opps became part of Germanwings, Long Haul stayed with Lufthansa. Until they axed them too! I expect we will some some announcement after Airport expansion is decided.
