It turns out VA was going to wet lease 4 320s from Aer Lingus who would crew and fly those jets. But that won't be possible if BA's gets control of those slots. Seems VA doesn't have any scope provisions either if Aer Lingus was going to do the flying. At least that was my interpretation from the Aviation Week article.
