The significant pending snow storm destined for the East Coast of the US is leading BA to proactively cancel flights today.
You can rebook as follows:
If you have a ticket for Monday 26 January or Tuesday 27 January and are travelling to or from Boston, New York JFK, Newark, Baltimore, Washington or Philadelphia and wish to change to a later date. You can rebook to travel between Sunday 25 January and Friday 30 January
You need to contact your local BA reservations office to do this.
This is the current status of flights to JFK. It appears that both BA and AA flights for the afternoon/evening today are cancelled already.
Good luck to everyone in the area – stay safe.
