I've been using CoMETS for many years now and find it absolutely indispensable.
As an AA flyer, my #1 request is to add an Elite Qualifying Points field to the database record, with its own bonus percentage calculation field. As a kluge, I've been using the EQM field to record EQP. This used to be a reasonable (if a little confusing) work-around, since AA used to always award 100% EQM, so the real EQM was always identical to the BIS miles. However, AA has jumped on to the Double Elite Qualifying Miles bandwagon, so it really hurts not to have a separate EQP field.
There was
discussion of adding an EQP field, back in March 2007 (has it really been that long?). If there's any way to get an update with an EQP field, you'd make all us AA fliers very happy.
