I am planning a trip with my family this June. I am considering booking a flight on United Airlines from Dublin to Kansas City, via Chicago. I am American, and my wife and sons are Irish, so unfortunately we have to go through the slow queue at Immigration. I know I can check us in all the way to Kansas City, and I have been assured that the United flight (operated by Aer Lingus) will preclear U.S. Immigration in Dublin, so the only holdups once I get to Chicago will be be customs, security and changing terminals (from Terminal 5 to Terminal 1 at O'Hare)
The plane from Dublin is scheduled to land at 3:10pm - My connecting flight to K.C. is at 4:55. At first that seemed like an adequate connection time, but now I'm starting to worry that it's cutting it a bit close. The last time I flew back home we missed our connecting flight because of the nightmare immigration line at Newark. Even though we will avoid the Immigration chaos in Chicago, I am very keen not to leave anything to chance this time. There is a distinct chance that the flight from Dublin to Chicago might be delayed, and if it is, that 100 minutes might dwindle down to an hour or less. There is also the concern of delays due to whatever security measures have been added since last Christmas.
I just need to know how long it should take us (assuming we're precleared by Immigration), to pick up our bags, carry them through customs, put them back on the belt, get through security, and take the airport link to Terminal 1. Is 1 hour 45 minutes enough of a buffer?
If anyone has any experience with a similar situation, I would like to hear it.
