I believe EI-FAW is due at anytime now and may have even been delivered to enter service tomorrow. It would kind of make seense to remove the odd balls in the fleet.
EI-FAX is due in December so would assume that EI-REI will also be leaving the fleet.
What you have to consider that EI-REI & EI-REH are both odd balls in the EIR ATR-72 fleet and this move will actually bring some commonality.
I was under the impression however that they were owned by Air Contractors so suprised EI-REH went to Toulouse.
