Per the
AI website, there may be a few contact options to try (in order of importance):
- Missing Miles / Retro Credit on AI: [email protected]
- General Enquires: [email protected]
- Missing Miles / Retro Credit on Star Partners : [email protected]
I'd recommend starting with the first email address and then wait a couple days (remember they're a day or so ahead of us) to see how they respond.
I've had a similar issue happen to my colleague 2 months ago although it was with a SK/LO itinerary where the LO portions got credited correctly but the SK portions weren't. For him it was critical since he was literally 500 miles away from re-qualifying to Gold for 2019 and he took that flight at the end of December. Short story long: he filed the missing mile request 14 days after taking the flight (as before) and received a similar error. I told him to wait a week and try again. When he did that the system was able to "find" the missing miles. Knowing AI and other * partners, it may very well be the case also that you need to wait longer than the 14 days UA suggests for UA to see the missing miles!
Hope that helps!
