I just enrolled in United's 1K Challenge.
Terms:
35k PQM or 40 PQS over the next 90 days.
United or COPA flights only
No mention of class of service bonuses being excluded from the challenge
Had to send MP my most recent AA EXP statement showing my EXP status (which was comped to me last year during the 1K -> EXP compfest). Time to get in the air.
