Did JL not allow NRT/HND transfer as it's own rule when a JL flight is involved? Asking because I've been having hard time trying to ticket a trip (far out in future) but whenever NRT/HND is involved it errors out last step.
Everything works when searching but seems to be some kind of rule being placed on TYO transfer at the moment?
There should not be. Even with Japan at its most restricted period, people could book HND/NRT connections and then complained when they could not fly them.
Do you leave enough time between flights?
