Well, there's the marauding male I might meet on the plane who'd like a deep and meaningful one night relationship, but usually once I've collected my luggage I get whisked away by a minder, so it isn't a problem. Anyone who talks as much about her husband and boys as much as I do, has no trouble, except boring the listener. An author is a one person business, even if you have an agent. So keeping up to date with emails and administrivia while you're on tour, especially in remote locations is important. I email from airport kiosks, use the mobile or phone cards and allow for time zone differences.
Internet access is brilliant.
I have to keep in contact with publishers, my agent and co-writers. It takes at least a day to prepare and another to follow up on long trips. I work like crazy before I go, to meet any deadlines, so I can travel without extra stress. My best airport experience was being the only passenger in First Class when the engine broke down in Bombay and I got to stay at the poshest hotel in India for 24 hours. My worst airport experience was when I boarded the wrong plane.
