We briefly review the current status of standard oscillations of atmospheric neutrinos in schemes with two, three, and four flavor mixing. It is shown that, although the pure νμ-->ντchannel provides an excellent 2νfit to the data, one cannot exclude, at present, the occurrence of additional subleading νμ-->νe oscillations (3νschemes) or of sizable νμ-->νs oscillations (4νschemes). It is also shown that the wide dynamical range of energy and pathlength probed by the Super-Kamiokande experiment puts severe constraints on nonstandard explanations of the atmospheric neutrino data, with a few notable exceptions.
