Frankfurt Airport is the main gateway for transcontinental flights, although Düsseldorf and Munich also receive their share of overseas air traffic. Until the opening of the new Berlin Brandenburg Airport, flights to Berlin will arrive at its two smaller international airports, Tegel and Schönefeld. There are also sizeable airports in Hamburg, Cologne/Bonn and Stuttgart, and smaller ones in such cities as Bremen, Dresden, Hanover, Leipzig-Halle, Münster-Osnabrück and Nuremberg.
Lufthansa, Germany's national flagship carrier and a Star Alliance member, operates a vast network of domestic and international flights and has one of the world’s best safety records. Practically every other national carrier from around the world serves Germany, along with budget airlines Air Berlin (www.airberlin.com), EasyJet (www.easyjet.com), Flybe (www.flybe.com), airBaltic (www.airbaltic.com), Ryanair (www.ryanair.com) and Germanwings (www.germanwings.com). Note that Ryanair usually flies to remote airports that are often little more than recycled military airstrips. Frankfurt-Hahn, for instance, is actually near the Moselle River, about 110km northwest of Frankfurt proper.
Timing is key when it comes to snapping up cheap airfares. You can generally save a bundle by booking early, travelling midweek (Tuesday to Thursday) or in low season (October to March/April in the case of Germany), or flying in the late evening or early morning.
