Oakland International is one of three airports serving the Bay Area.
Just your average airport, not much for the children to even look at let alone interact with. I've used this airport several time and it isn't very easy going. Its always crowded with no crowd control so i worry about my children being safe and comfortable. Staff tries to be friendly but i definitely wouldn't choose to bring my kids along with me at this airport. My children seemed bored and there wasn't even a child friendly restaurant. I would not recommend families fly out of this airport, San Francisco has a much friendlier and kid friendly environment.
We were traveling from Oakland to Washington DC. At the time, our son was only 16 months old. We had a delay that morning which was out of our control, obviously. There is not much to do at the airport so be prepared. Thankfully we had coloring books and activities.
This is an airport in transition. OAK is under renovation, and I hope it comes out soon. There are some nice features for families here: A dedicated family security line with a couple screening areas, nice selection of food after security representing local favorites (including a Fenton's Creamery counter if you are so inclined or want to use it as a reward for good flight behavior). There's some beautiful art to keep babies entertained. But many of the bathrooms lack changing tables and folks always seem crowded into the flight receiving areas. Children can be looked at with disdain by the business crowd and strollers are hard to maneuver at times.
