i had no idea that i was following a wikipedia guide

I like it how airlines are trying to play the legal card. Screw them! They tend to price everything backwards and then charge you extra for fuel!
My ticket is going to be one way, as I will be using ground transport, mostly car rental for the rest of the trip, primary because I want to avoid TSA harassment.. I will be flying back to Hawaii from San Fran.
I am sure I will have more questions about airports later on.
BTW, changing the rest of the itinerary is brutal, although not relevant to my case. What if I missed connecting flight not on purpose and took next available from another carrier?
