We're flying with TC to Heraklion in September; it's a TC package holiday, if that makes any difference.
I've been looking for information on how long in advance I can do online checkin.
Some places say beween 7 days and 24 hours before, others between 48 and 24 hours before. The TC help pages, though carrying information about OLCI, don't actually mention time limits.
Has anyone done OLCI with TC recently?
