As someone who's addicted to flight deals, I pretty much have alerts set up on every airline website so I can always know the best deals.
And this is definitely one worth mentioning.
Porter airlines is holding a special 2 day sale and you don't want to miss out on this one.
If you book your flight before Tuesday April 5th (departing before July 27th) you can take advantage of some serious deals including Montreal to New York for about $200.
There are also great deals to Toronto, Boston and even Florida.
