The last three times I’ve had international flights, the puddle jumper connecting flights have been so delayed that I missed the connection. It seems like the big flights rarely get delayed, but God help you if you need to fly from, say DC to Philly (145 miles) or Baltimore to New York (250 miles).
On my next-to-last trip, it took American 13 HOURS to get me from DC to Montreal (450 miles). And they lost my luggage. Literally, I could have taken the bus faster.
It’s gotten so bad that I no longer take the puddle jumper flights. I now book to fly directly out of Dulles or Philly or New York and just drive there, or take Amtrak. It’s both faster and cheaper.
