I read this thread to see what people are experiencing with the aisle/window only request being made during OLCI. I'm flying DL for the first time in a long time tomorrow and as a silver elite I'm not eligible for C+ or F upgrades on my connecting flight yet as it's 24+ hours away.

I'm starting with SEA-SLC and I declined a C+ upgrade through the website days ago when I saw only middle seats were left in C+. My exit row window for a 1hr30min flight is perfectly fine for me. During checkin it offered me the option to select C+ aisle/window only so I did that. Now I'm #1 of 1 on the upgrade list for C+ which has 8 seats open and all middle seats.

If an aisle/window opens up between now and before I go to the airport tomorrow, will I automatically be upgraded into it (assuming I'm still #1 and that the upgrade inventory bucket is opened between now and then)? Or are requests for only aisle/window upgrades processed at the gate? And does the gate agent see I only want an aisle/window or do they simply upgrade me into any seat before boarding because I'm on the upgrade list? First won't be an option on this flight as it will go out full with several golds (and maybe plats) not upgraded.

The connecting flight is an E175 so only aisle/window C+ seats offered on that flight. I'm fairly confident my upgrade to first will come through as there are 8 out of 12 open seats (and 8 for sale) and I'm #1 of 3 on the list for that one so far.

Gone are the days when DL used to process upgrades a full day ahead of the published schedule? It used to be silvers were processed at 48 hours, golds at 4 days, etc.

Thanks,
