My code says it was already redeemed and I can’t reuse it, even though I haven’t and it says someone already put it on their steam account.
Exact same probleme here.
No steam codes have been released for this weekend’s flight. The code you are trying to use is for an older, closed flight - likely MCC Season 8.
The flight is on hold at the moment as 343 are dealing with a late-game technical issue. No codes or emails providing access to builds are likely to be sent until decisions have been made and updates posted. An update is likely to come out in the AM, 343 time [PST] with further details.
