I had a trip scheduled on United from MSP to ORD to OGG last week. It was cancelled because of weather (the skies were clear by the time we would have departed). We were then put on a flight from MSP to PHX to OGG on US Airways. This too, was cancelled, but for mechanical reasons. Then we were put on a flight from MSP to SFO to HNL on Delta and then to OGG the next morning on Hawaiian. Miles have not posted for the flight. Since four different airlines were involved, where do I go to get mileage credit. Can I get United Miles for Delta flights I took? Or since they are not partners, should I request miles on my Delta account? My first choice would be United miles, second choice would be Delta. Thanks in advance.
