I've claimed a few flights with Delta. All seem to have gone through easily, except for a TIJ-MEX-HAV flight. I emailed them the details separately, and they said they've put them through manually.
After a few days, both show up (business) and the TIJ-MEX leg has points credited, but not the MEX-HAV leg. Is this a America-Cuba relations thing, or just a Delta mistake?
(I know I can email them and ask, but I like to know what I'm talking about before I contact them)
