The key to 5/7 means that NWA has probably got an Atlantic configured 757 completed by now and is flying the system. Or, it could mean that they're not going to put it into revenue service until the flight leaves tomorrow night for FRA. Either way, as soon as someone flies it, a report on the WBC seat and ammenities in coach needs to be posted!

Flew DTW-FRA on the 333 today and saw a wingletted 757 in DTW on a hardstand near one of the hangars. I assume this is a newly re-configured bird getting ready for the FRA flight. As I got off the plane, I overheard an FA saying there were bringing 21 crew on the flight (for the return 757 flight, I assume). Finally, AVOD systems were dead on rows 19-28 for the entire flight. We got 5000 mile/$50 off vouchers, but it was one boring flight.
