I don't think there are any "gimmes" for a PM based in the DCA-IAD area these days.
I'm 3 for 9 since being relegated to PM. My successes were:
DCA-JFK (K fare, cleared at window) 3/7/19
JFK-TPA (K fare, was
#2 on the UG list, I got the last UG) 3/7/19
SLC-SMF (L fare, was
#2 for 5 UGs) 3/8/19
I was #5 for 0 seats TPA-DTW 3/7/19
I was the bubble boy DTW-DCA (last flight of the night, 2 got UGed at the gate, 1 got UGed after boarding) 3/7/19
I was #8 for 3 seats IAD-SLC 3/8/19
I was
#13 out of 38 for 0 seats SMF-ATL.3/10/19
I was
#2 for 0 seats ATL-IAD 3/10/19
I was
#4 for 0 seats IAD-ATL 2/20/19
I've flown out of IAD on three different trips since the beginning of 2019. Load factors appear to be quite high. This past weekend, IAD-SLC had 4 empty seats in C+ with the other cabins sold out on an A320. There were 8 empties in Y ATL-IAD on an MD-88 with the other two cabins full. I wish that Delta could take the VS clubhouse and turn it into a SkyClub. it is a shame that this club isn't utilized to its full possible use.
