I really thought I was flying my United Airlines flight from Oakland airport, but when we got there, I was surprised to find it wasn't there but San Francisco International! I felt really bad because I double checked my flight details but kind of overlooked the departure airport. Good thing the United guys from SFO Intl were very good, the rebooking was quick and most of all it's free! Will definitely fly United again, they have shown sensitivity to their passengers' needs and limitations. My trip to NYC is definitely more memorable because of my great United experience!
