In anticipation of the arrival of Hurricane Sandy, the nation's airlines canceled about 9,500 flights on Monday and Tuesday, mostly along the East Coast.
The greatest number of canceled flights were from Philadelphia International Airport, Newark Liberty International Airport, La Guardia Airport and John F. Kennedy International Airport, according to the air travel tracking site Flightstats.com.
Because the storm is on a path for the nation's busiest airspace, the impact of the cancellations has already begun to spread around the country, including 81 canceled flights into Los Angeles International Airport and 84 into San Francisco International Airport.
The nation's airlines canceled about 1,800 flights on Sunday, nearly 8,000 flights on Monday and have already canceled an additional 1,700 flights scheduled for Tuesday, according to Flightstats.com.
Most major carriers are waiving the fee they charge passengers to rebook flights but only for specific flights canceled due to the storm. The airlines urge fliers to check their carrier's websites to make sure the fee waiver applies to them.
