I flew into MSP today from ATL and had a break and went down to the crewroom under F11? Anyway, some DL-N pilots were upset with the new AWABS system, and one said he had heard that we were going to go back to the former NWA system in 4 months, since it supposedly "saves more money" in gas savings. I stated I did not see that, since the cost indexes are lower on the new system, being in the teens compared to always 55 on some NWA software. I would think they will waste more money training the majority of DL pilots (S guys) to the NWA system, and more paper, since I watched a DC-9 crew in MEM get their paper work last week and it seemed like a ton.
