Not worth it just to pay cash for it. For me, a big part of flying 100k EQMs is earning 200k RDMs (moving me closer and closer to 2MM and Lifetime PLT).
After all, EXP status doesn't mean anything unless you are traveling on AA or a OW partner.
Plus, without doing MRs, how are we going to make use of those lovely eVIPs? (Gotta have those signature sundaes!)
