After the Airbus year end press conference there was the announcement that Virgin America would purchase - and already signed a firm order - for 30 A320NEO's along with 30 "classic" A320's.
Although this order seems insignificant in size compared to the IndiGo deal last week for 150 A320NEO's, it is indeed significant as it is a firm order, in contrast to the MoU signed by IndiGo.
Virgin America made no engine choice so far, but hopes to decide on the engine by May. This could be the first order for a NEO engine then and could give us some hints. Virgin now operates CFM56 on their A320's.
Expect more orders to flow in for the A320NEO in the next weeks!
