...and a warning....
TWICE, two separate trips, we have tried to use boarding passes issued by the WL "on the door" system. TWICE, two separate trips, they have been rejected at MCO as "would not scan".
Today? We check in to the airline on the Web. GO to the Concierge. Given an airline, and a conf number? THEY will print boarding passes. Boarding passes that actually WORK. No "will not scan" garbage that will send you back to the airport check in desk.
You may do as you wish - but we have data indicating a less than 80% success rate with the "hang on your door" junk. 100% success with Concierge printed boarding passes. 12 years, two trips per year.
