I'm second-guessing myself - my flight is scheduled to arrive at O'Hare around 9:30 am. If all goes well, that leaves plenty time to get to Union Station via the metro and on a train departing at 2:00 pm, but now I'm worried about flight delays, etc.
Can you reassure me that I'm worrying for nothing?
Worry if you must. The odds are greatly in your favor. The upthread posters say so, and in my limited experience at O'Hare, they are correct.Have a Plan B, in any case, it reduces anxiety, if nothing else.
If you like to worry, I could tell you about 3 times flight delays at O'Hare worried me. Two of those were in winter, so don't apply. (I did sweat wooden nickles when my early teen kids were delayed by freezing fog at O'hare - but that was misplaced worrying)
My worst bad flight thru O'Hare (really really unlikely) Last May 12 - in the evening - the whole central USA erupted in thunderstorms. Delayed arrival 2 hours ORD at 16:something. Thunder, lightening, horizontal rain squalls blasting the concourse windows. All connecting flights (including mine to STL) delayed or cancelled, . Slept from 01:20 to 04:20 on the CDA folding cot with their welcome blanket and pillow (and an amenity kit, also, with wet-wipes,toothpaste, etc) (all hotels sold out)
At about 05:something airline told me I might get to STL by 10-11PM - so I called Julie , got AMTRAK ticket onward to Saint Louis (where I wanted to get to) Rode the Blue El to CUS, plenty time to catch the train (Lincoln service 7am .
On AMTRAK Lincoln service at Springfield, learned that disgruntled ATC employee started fire in air system at Air traffic Control. All flights delayed another 8-10 hours. I coulda stayed at O'Hare another 20 hours and flown to STL, but glad I didn't, took AMTRAK instead, caught up with my itinerary
So, if you want to worry, consider that. (Really exceptional, unlikely, but possible O'Hare problem)
Really, with a scheduled 5 hours to connect, (almost) zero worries.
Check the weather forecasts, don't perspire.
