Other European Frequent Flyer Programs - Icelandair and Cheaptickets.com

In a few weeks, I'm traveling BOS -> LHR on Icelandair via KEF (really low fares on Cheaptickets.com).

However, the only info I got from Cheaptickets.com was a 13 digit "ticket number" and seat numbers. The ticket number isn't a booking code, so I can't look up info, confirm reservations, or check-in with Icelandair.us. (The last of these isn't surprising, since I don't think ICE does online checkins from BOS)

Should I be worried here? I'll probably call Icelandair's phone number in a bit and doublecheck everything.

Probably no reason to worry, but I'd definately call them. Icelandair does not do on-line checkin on US flights, but does do so on their European flights.
