On www.delta.com vs. the APP, MQM, MQD post in odd ways [based on my one trip post 4/1 for A-B-A]
www.delta.com: each segment shows the regular and accelerators for MQM, MQD separately listed and then a grand total--all of these appear to be correct.
on the APP: only regular MQDs are listed for each segment, both regular and accelerator MQMs are separately listed, the grand total (somehow) correctly lists the sum of both regular and accelerator MQDs [which agrees with the GT on www.delta.com]
