worth upgrading?
I bought a K fare SFO-EWR-GLA for travel 12/30. (return date is V fare). There are upgrades available to BF on the EWR-GLA portion but of of course the SFO-EWR is waitlisted. Is the SFO-EWR likely to clear before travel. I am silver so I'm unlikely to get EAU in the alternative.
Would you upgrade the international section and wait for the domestic portion?
