Sorry for not posting this sooner but here is the service schedule information for today courtesy of a press release sent to me by the MTA:
MTA New York City Transit and MTA Bus officials today announced service plans on subways and buses for tomorrow’s Thanksgiving Day holiday.
On Thanksgiving Day, Thursday, November 26th, New York City Transit subways will run on a Sunday schedule, with additional service provided on select lines before the Macy’s Thanksgiving Day Parade. At the conclusion of the parade, some express trains may run on the local tracks to absorb the crowds from the parade.
Buses operated by MTA New York City Transit and MTA Bus will also run on a Sunday schedule. In addition, bus routes along the parade route in Manhattan will either be detoured and/or severely delayed.
On the Friday after Thanksgiving though, subways will operate on a regular weekday schedule, while buses will operate on a reduced weekday schedule.
