Don't expect EI to be picking up the slack from Thomas Cook in any significant shape or form. The business plan is now heavily focussed on growing ACMI. The benefits are that its low risk and provides guaranteed revenue. Leasing new aircraft to serve additional routes would mean someone is putting their neck on the line. Should there be demand on any overlapping Thomas Cook routes and larger aircraft be available then they could conceivably be switched to free up additional seats. Like most airlines the summer has the aircaft and crews maxed out just servicing the existing schedule.
