I’ve been GM or higher since 2011, but find myself an FO for 2019 (I went for the lowest cost flights in 2018).
My first flight on DL this year was today, MSP-PIT (728 air miles) on a CRJ900. I was upgraded to C+, and had a row to my self (many empty C+ seats around me).
I turned down an upgrade to 1st Class because it was a single seat on the port (left) side. I did a quick risk assessment and decided that the C+ seat was better.
Sorry to let down all the other FOs out there.
