actual flight miles for delayed and circuitous flight?
 

I flew DTW-IAH last week, but due to thunderstorms, we flew from DTW to IAh to New Orleans, landed and refueled, circled back to IAH, down to Corpus Christi, took another approach, and finally landed in IAH almost 5 hours late.

My question is, shouldn't I get the actual mileage flown, not just the standard DTW-IAH miles for an uneventful, regularly routed flight? That's all I've been credited so far . . .

Unfortunately it doesn't work like that - your flight segment, while it included MSY and a lot of flying around, was only DTW-IAH - just like if you buy a direct flight from HNL-DTW that actually stops in SEA - you only get the HNL-DTW mileage anyways.

And, since it was weather, talk-to-us most likely wouldn't lead to any bonus miles - sorry

I was flying DTW-AMS back in June and had a diversion back to DTW over Newfoundland - about seven hours of flying to move one gate at DTW. Did not get anything when I asked for an extra segment of DTW-AMS. They did give out vouchers on the plane.
