50 min connection time at IAD
 

Is 50 min enough time to connect at IAD? Arriving at Concourse D from a transcon and connecting to councourse A on a united express.... mid week around 4pm...

I am thinking it is cutting it close but if it is feasible it provides me with ideal departure and arrival times

thanks for your input

First of all, not all UX flights operate from the A gates - some use a few of the higher-numbered, even-numbered C gates.

Second, the shuttle from D to A only operates during 4 busy periods of the day (probably including your arrival time). But that shuttle usually only leaves every 8 minutes for a 4-5 minute ride. If you arrive at one of the low-numbered D gates (definitely D1-D7, possibly the higher ones too), you would be better off hiking into the connected C concourse and taking the C-to-A shuttle (leaves every 5 minutes for a 2 minute ride).

Finally, if you arrive 10-15 minutes early you should have no problem. If you arrive 10-15 minutes late (and the connecting flight is leaving ontime), hope you have a backup plan.

The key to tight connections.
