Warning!!!!! I had an old passport a year ago, flew to LA simply to get on a connecting flight to Mexico and ended up spending 7 hours in the immigration office, missed my connection, had to stay overnight in LA after being given a temporary visa and a fine, nearly missed the wedding I was going to in Mexico AND was rerouted back home via Canada as the US DO NOT allow unchipped passports!!!! It was very stressful, expensive and intrusive, an experience i wouldnt wish on anyone. Get a new passport!
