Airlines are still operating flights into and out of Japan as concerns over the aftermath of a devastating earthquake and the subsequent alarms over radiation leaks increase.

Most airlines have resumed regular air service, particularly on international segments to and from Japan. Though air traffic was greatly affected on 11 March when a 9.0 earthquake shook the northern region of Japan, most airlines have resumed operations and flight schedules are close to normal for many. Several airlines are waiving fees and restrictions on ticket changes. Several countries have issued travel advisories for their citizens who may be contemplating travel to Japan. This may affect passenger loads and cause some airlines to adjust schedules or cancel flights based on demand. Below is an alphabetical listing of known advisories.
