SEA resident; business travel is 1-2x monthly RTs to WAS and 3-4x annual to LA, leisure is maybe 2x/year TCON and one or two other domestic, with an international trip every 3-4 years … I’ve held DL PM for 10+ years and AS 75K for about five
I get a lot of the qualification miles by paying out of pocket to upfare work travel to F, esp on eastbound redeye TCONs; have used AA the last two years to fill in when AS seasonally drops SEA-IAD/BWI redeye service (and DL lie-flats to BOS/JFK are often exorbitantly priced)
