I think there are so many good opportunities for RE to take advantage of. I've thought for a long time that they should do ORK/LTN or LCY (especially now Jetmagic are gone) despite the indirect competition with FR ORK/STN. Also, ORK/NCL, ORK/AMS, ORK/CDG (morning and evening) would fit in to their network quite nicely, as would the likes of DUB/HUY, DUB/NWI and DUB/DND (with a bit of advertising at both ends), in my opinion.
I think RE are a nice little outfit that have worked hard to do well and I hope they continue to do so.
