Was flying from CSG to SDF with a connection in ATL Friday. CSG to ATL got cancelled (last flight of the day). Had to drive to ATL to catch my 7:05pm connector which I couldn't make it in time and was rebooked on the 8:35pm to SDF.

At the ticket counter the agent put me in 24D, she tried to put me in 10C (EC) but it was blocked. I get to the gate and ask to be moved to 10C but the GA says she has to leave it open in case they have a disabled passenger but she said she would keep me in line in case there wasn't. Only other EC seats were middle rows. I'm also #1 on upgrade with 1 seat remaining.

While I'm sitting I notice that the entire row 10 has been filled with standby passengers (there were other open seats). I approach the GA and she basically said too bad. The GA was rude and unhelpful. I find a red coat and he fixes it. The GA gives some BS excuse and I call her on it. The red coat tells the GA she should have gave preference to medallion members.

Finally, as the flight is boarding they still haven't cleared the final seat in first> I suspect she knew I was #1 on upgrade list and she had no intention of upgrading me until I asked her when she plans on clearing the final seat. She does and I board.

Anyway, should I send an email to Delta for this? While I don't want to come across as a DYKWIA, Delta and I have an agreement, in consideration for my loyalty to their airline they agree to provide me certain benefits (perks, upgrades, EC seats, etc). I think the GA failed in this regard. They represent the company and this type of behavior and disregard for their loyal customer is bad for business.

Thoughts?
