I got a similar call from an AA rep who started out saying, "I think I know why you're doing this, but if you like I can give you a better routing on your flight" (which is ICT-DFW-SFO-BOS-SFO-SJC-SAN-DFW-ICT). She just laughed when I politely declined and said, "well, I thought so, but had to ask".

What do you think? Are they always looking at weird routings? Some kind of security check? I wonder why/how all these flights came to their attention and why they're calling. This must be new, but MRing certainly isn't.
