Due to the week-long school closures from Hurricane Sandy earlier this year, many schools, including NYC Public Schools, have pre-emptively cancelled or shortened their planned February 2013 school breaks.
For families with kids planning to travel during this period - probably traveling on non-refundable economy tickets - this change in school schedule could cost them a fortune in change fees (imaging the fees from changing flights for parties of 5 or 6 people!).
American has announced that they will give a one-time change fee waiver for any ticket for flights departing LGA/JFK/HPN/EWR between February 15-24, so long as your ticket was issued prior to November 29. While they still require travel one-year from date of original issue (not too helpful for those who book 330 days in advance), for many, this waiver will represent a big savings - and will probably keep a few more kids in school!
Nice move AA!
