Due to lower charges and greater capacity in the pre clearance, it was SNN they looked at. Negotiations were going on at senior level, but FR decided against it.
EI out of ORK to JFK is plausible I suppose, but they didn't do it with their 767s, not doing it with their 757s, maybe with an A319 NEO if they go for them, who knows.
Hopefully some good news for ORK will come down the line soon, but it looks very much like they are in a scrap with SNN
