This had nothing to do with Delta! When my area was called to board, as I got up to walk, something snapped in my foot, I was in pain but managed to get on board. The flight crew were great & helpful, got me a wheelchair etc., helped get my bag. I sadly spent the next 6 hours in the ER once I got home. Compared to some of the other airlines operating out there, Delta & American really rock!
