I agree with you 840.
I think a 5th EI unit in ORK would do just fine, it would allow double daily on BHX and MAN every day - should that be necessary. What other routes could be launched which would be successful right now though, Im not sure. Perhaps LGW - although this might hurt LHR traffic, other options would be PRG, CPH/HEL, FRA and possibly somewhere like Malta, Cyprus in Summer.
