We just got back from WDW Saturday night (2/11). When we checked our bags at POFQ and got our boarding passes, I just put them in my bag and went off to the parks. Other than glancing at the top one to make sure the departure time hadn't changed, I didn't bother to look at them, until we were on the DME bus back to the airport that evening. When I finally looked at them, I found American Airlines had split our party up (placing my 3 y/o GS alone in row 18, me in row 22 and my husband in row 24).
I had purposely booked us in Row 17 Seats A, B, and C, when I booked the flight several months ago. As soon as we got to the airport, I went to the American Airline desk to get it straightened out and they told me they would make a note of it in the computer, but I would have to have the gate agent straighten it out. The gate agent was able to get me seated next to my grandson, but said she couldn't move my husband, but not to worry about it and to just ask the person sitting next to me if they'd switch seats with my husband. She assured me that since my husband and the person next to me both had an aisle seat and the rows were only a few rows apart the other person would switch with him. I was not happy with that outcome. I was polite, but let her know that since I had paid for seats together, that I expected them to fix their mistake. She could not tell me why our seats were switched around.
Thankfully a little while before boarding, we were called up to the desk and were moved to the first row in coach in seats D, E, and F. The gate agent informed me I should have checked the seats as soon as RAC handed them to me, to make sure they were correct. They never could explain why our seats were switched around though. I had checked them prior to leaving home the Sat before and they were fine. There was also another family there at the desk complaining that their seats had been switched around and they were no longer seated together either, even though like us they had chosen seats together.
