Those who are exempt from baggage fees are:
- MVP

- Confirmed in First Class at check-in
- Within the state of AK
- To/from Guadalajara and Mexico City
- U.S. military personnel on orders
2.) Those allowed through the premium security line in Seattle:
C-concourse Checkpoint:
MVP Gold
First Class on AS
QX Shuttle Passengers
D/N Checkpoint:
MVP Gold
First Class on AS
UA First/Business Class
UA Premier Exec, 1K & Global Services
Star Alliance Gold
WN A-list and BS customers also get priority at the C checkpoint.
I think the vast majority of DL pax use the A/S checkpoint, which doesn't have a priority lane. Whenever I have a red-eye flight on DL, I always schlep over to the C checkpoint (which is practically dead after 9 pm) to avoid the hoards at A/S.
