I just got back from RDU and on my way down there while I was waiting for my CO flight I saw what appeared to be an ex-DL 737-200. The plane was completely stripped except for the tail rudder which had the wavy gravy scheme as well as one of the engines which still had a little bit of DL paint. This was around 10am on Thursday 8/23.
Also last night when I arrived in EWR there was a plane at terminal B where DL/YX/NW are that had a blue tail that had XA on it. I couldn't tell though which airline it was. I saw it taxiing for departure around 8:20pm. I think it was a 737-300.
If anyone has any information on these planes I'd love to know. I've never heard of XA and am very curious as to who ws operating that 732.
