Aer Lingus was unable to give IAG the confidence it needed in our cost structure, resulting in the inaugural A321 XLR – originally planned for Aer Lingus –being allocated elsewhere in the group," the airline said in a statement. On the same basis and given the deadline for a decision on painting was this week, the second XLR aircraft will not be painted in Aer Lingus livery and will remain available to be allocated elsewhere within the group."
