I have never seen an airport in Lichtenstein. I dont even know if the damn place is long enough for 10000ft runway. I doubt it wide enough. I suspect that you were flying into CH (Zurich). Just some uselss trivia. Lichtenstein isnt big enough to take care of many govt functions (i.e. license plates) and they outsource to CH.How efficiently German! :rofl:
Anyway, I find that even a cheaper flight is generally only nominally so. Sometimes having a flexible schedule helps, sometimes it doesn't. Sometimes buying far in advance is helpful, other times not. It seems that you're more or less at the mercy of seasonal price fluctuations, though for spring break 2010 I flew to Spain and back for about $650, while the flight for the same period this year looks to be around double that. I've already got my tickets for this march to visit the girlfriend's sister near Frankfurt, which cost about the same; so that hurt.
Also, perhaps some airlines serving the area in which you'll be traveling offer a feature like SwissAir's website. It allows you to view a map where you can manipulate the departure and destination airports to very easily compare the fare costs, typically comparable to other airlines' fares for the same two airports. When we were originally going to Germany in a different month, it turned out that a flight to Liechtenstein from Atlanta was about $400 cheaper (!!), and even with the flight to and from ATL, and train fare once in Europe, would have been pretty good savings. Could've been a one-time thing, but who knows?
