This happened to me for the first time yesterday, so I'm not quite sure what to expect. Flying SFO-JFK-DCA. When we landed in JFK, got word that JFK-DCA was cancelled (Eagle) because of weather from TS Beryl along the east coast. AC AAngel rebooked us on a US Airways flight out of LGA, and got us a car voucher to get between airports. The US Airways flight was diverted en route, stopping in RIC to refuel before going on to DCA. Should I still get credit for the JFK-DCA flight? At the 500-mile minimum?
