Good to know. Thanks!
Speaking of waitlisting, though: is it possible to request to waitlist on this flight? Or, for instance, this segment is currently confirmed on LX F on the old 343 equipment, but ZRH-ORD is in LX C because there was no F space available: can United add me to a waitlist for F space on LX, or do I have to keep checking and calling back?
