Four giant airline computer systems in the United States handle nearly all the airline reservations in the country. (They're known as CRSs, for computer reservations systems, or more often now GDS for global distribution systems.) Although each airline has a ``home'' CRS, the systems are all interlinked so that you can, with few exceptions, buy tickets for any airline from any CRS. The dominant systems in the U.S. are Sabre (home to American and US Airways), Galileo (home to United), Worldspan (home to Delta, Northwest), and Amadeus (many European lines.) The company that owned Galileo and Orbitz recently bought Worldspan, so the two GDS will presumably be merged. Many of the low-price start-up airlines don't participate in any of these systems but have their own Web sites where you can check flights and buy tickets. Southwest, the largest and oldest of the low-price airlines, doesn't participate, either. Southwest's web site gets car and hotel info from Galileo, but the info seems not to flow the other way. Orbitz one of the big three online travel agencies, runs its own system which is "direct connect" linked directly to many of the airlines.

IMPORTANT NOTICE: Canadians travelling for tourism purposes in a European Union country must hold a passport valid for at least three (3) months beyond the date of expected return from that country (exceptions: United Kingdom and Ireland require a valid Canadian passport only). For sun destinations, the validity period must usually be at least six (6) months beyond the date of expected return. Regulations may vary for non-Canadian passport holders.

Other changes include: some airports have stopped curb-side baggage check, anything vaguely resembling a knife or lighter may or may not be confiscated (although lighters suddenly stopped being dangerous a year ago), you're sometimes only allowed one carry-on plus a purse, briefcase, diaper bag or the like, non-passengers aren't allowed past security, all passengers must have a document that looks like a boarding pass at most airports to get past security, you may have to put your toothpaste and shampoo in a baggie that may have to be a one quart size, some parking areas close to terminals are closed. But check-in clerks no longer ask you whether you packed your own suitcase.
