(Of course, I hear at NWA you still manually write trip pickup requests on pieces of paper that the midnight scheduling shift in MSP processes....? True? It's all computerized at DAL and has been for many years.)
Umm.....No. We have been submitting schedule adjustment requests(trip trades, pickups, drops etc) via computer for many years. Booking jumpseats online too!
The trip trade requests ARE processed each midnight in MSP though, as you said.
