In a few weeks, we're flying DL through ORD-JFK-PRG. We have an early afternoon flight for part 1, and the JFK-PRG departure isn't until 7:48pm. I've been tracking the flights to see the reliability, and our first leg has an on-time of 55%. At this moment, we have a 4 1/2 hr layover built into our connection. Just curious after yesterday's headaches at JFK b/c of weather, if they cancel DL210 (JFK-PRG) will they rebook on another carrier? I saw DL210 pushed back departure until 2:30am-ish when it was then cancelled. Today DL211 the return leg from PRG is cancelled as well. We haven't gone int'l. in sometime (aside from military airlifts) and I didn't know if DL would rebook on another carrier b/c of weather. Thanks for putting our mind at ease.
