Midwest - 42 minute connection in ORD for intnl - enough??

I just got booked through work on UA from SFO - ORD and then ORD - CDG. Connection as listed is only 42 minutes. UA says it is a "legal" connection, but that doesn't seem like enough to get through ORD, especially to get to an intl connection. Has anyone else done this? Does it work out, or should I expect to run like mad through ORD? Or is UA padding arrival times so it's really more like an hour? Thanks!!

The flights will come and go from the same terminal. Possibly a different concourse although even the longest walk isn't more than ten minutes or so.

Certainly doable but if anything causes a delay you're not going to have any wiggle room really. Neither SFO nor ORD are known for smooth operations when there's any form of weather.

There's only one ORD-CDG a day IIRC but you have options via Germany and the UK to be rerouted if you miss it.

I agree this is likely a short walk, but don't take your time (no stops at the "wonderful" RCC...)

Keep in mind a delay in ORD might also give you MORE time to get your CDG flight.

It's tight, although doable if the flights are on time but given SFO etc, that could be a big if.

If you're worried about it & there is an earlier flight from SFO-ORD (and it's on a ticket purchased before 4/10, so no standby fee), I'd go to SFO & do standby on an earlier flight. When I was in LAX & doing LAX-ORD-Int'l or LAX-SFO-int'l, and they wanted to put me on a 45-minute connection, I always checked the flights before, the loads & went standby on earlier flight (which I always cleared). I'd rather hang out in the RCC than miss the connection.

Cheers.

You should actually be fine. Your flight from SFO will most likely land at the C concourse since those gates tend to accommodate the long-haul planes. I checked today's arrivals, and all but one land at C. C is also where the CDG flight will depart from, toward the middle of the concourse.

If there is any indication at SFO that the flight will be delayed, deal with rebooking there rather than waiting until you get to ORD.
