One thing is absolutely certain. There are NEVER going to be scheduled ops between GCI & LTN by 3 different airlines. Personally, I don't ever see more than one operator; & , even then, it won't be daily (maybe two or three times weekly); & it will only be a summer operation. Moreover, it won't last for much more than one season - IF it ever operates at all.
Could be wrong though. Although, I don't think so.
