So far with BA I've had a weather divert to PHL en route to JFK, fuel issue meaning a stop in LCA on the way out of TLV, and a pretty urgent landing at YUL on the way from YYZ to LHR due to incorrectly loaded volatile cargo. On AA I had a couple of hours on the tarmac at Shreveport, LA when flying NYC-DFW due to storms, and I've flown from Norfolk, VA to...Norfolk, VA due to weather in PHL.
