Looking at my (vacation) reservation on aa.com today, I saw there were some more desirable seats available on one of my flights. I clicked on the seats showing as available, click on submit, and get the message that "one or more of the seats selected is not available." ???? Both seats were showing as available before I clicked submit; both seats showed available after getting this messgae. Is Casper the Friendly Ghost sitting there? Has anyone else run into this? Or is this aa.com's way of telling me I am looking at that reservation way, way too often.....
