I have done some interim updates, keep the great ideas coming in, it really adds a lot of value when so many people pitch in. Thanks again for the all the kind words, but I highlight that I have been helped by other FTers and even the stuff that I wrote was probably lifted from someone else's original idea.
- many typos removed
- section 1 simplified and made less ponderous (since we ponder anew in post 12)
- a new bit about codeshares
- ditto one way fares
- discount arrangements (Forces, AARP)
- a few more tips on finding cheaper fares.
