In 2006, we were booked on Summit, leaving from Vancouver. BC.
Our flight from Philly was delayed 1-1/2 hours leaving for Chicago. Arriving 2 hours late, after deplaning, we heard our names being paged in concourse. We rushed to gate, were practically pushed on board the plane, the door was closed on our heels. The stewardess told us that the flight was delayed in hopes we would make it.
Next time, a day or two in hotel is the way to go!
