I'm flying in August from Richmond to Minneapolis via Atlanta. The connecting flight to MSP has an odd flight # "8773." It's a 757-200 and appears to be one of the 757's with the fancy inflight entertainment system.
It appears this flight is not part of the regular schedule but shows up from time to time at differing times of day but with the same flight #.
Any insights? I'm guessing some type of repositioing flight?
