First, are the runways open?
Next, is there public transit to get workers to the airport? If not, does the airline have enough staff staying at nearby hotels that can be bused in?
Finally, the airline has to check on all the other people needed to run an airport: the Transportation Security Administration, customs officials, caters, fuel trucks and even the people who push wheelchairs through the terminal.
Baker, the FligthAware CEO, notes that the timing of this storm does work in the airlines’ favor.
‘‘Fortunately, Saturday is the lightest travel day of the week, so airlines can use the day to restart their operations in time for the Sunday evening travel rush,’’ Baker says.
