SFO-JFK redeye canceled due to crew issue over the weekend. G75K if that matters.
1) $100 discount code for the cancellation.
2) Fare refund. (full disclosure: I reached out to AS both at the airport and on the phone - AS did offer me replacement flight options with other carriers next day/night. I politely declined them due to variety of reasons).
3) $250 discount code or actual reimbursement of out-of-pocket costs - e.g. overnight lodging. I took the former.
