It all depends on where you off to, and what you want out of the program. Join NW
as we do have one of the best progams where your not locked into a limited number of upgrades once you reach an elite level like on UA
. NWA also has the most number of FC seats on domestic narrow bodies (Airbus, and Dc9s all have 16 seats vs UA
which will have either 8 or 12) which means more chances to uprade. If your flying INTL, NW
is part of SkyTeam and you can use your miles on ANY member of SkyTeam for anything form upgrading, reward tickets etc.
