This doesn't have anything to do with the airport specifically...but avoid flying united airlines!!! They are terrible. Delays and cancellations, planes breaking down. What a mess.
Don't bother looking for free wifi. I walked up and down A and B and didn't find any. Starbucks didn't have any, even outside the airline clubs their wifi was still pay-to-use.
Worst experience at an airport ever! They trains were down for maintenance at 6:40 am instead of working to get people to their flights! Worst managed maintenance- thanks for making me miss my flight!
