Jets Go is offering a deal that will get you from Toronto to Montreal (or vice versa) for one dollar. The only catch is that you have to book before the end of the month and you can only fly between May 10th and May 15th. Other than that, one dollar to Montreal.
Though if you were to look at your calendar, you would notice that that period spans Monday to Saturday — so no weekend getaways. In fact, no weekend time at all as Saturday is out as all the (but one, at this moment) return flights for that day are booked solid. Still, if you can get some spare time during the week, it’s a really good deal. It’d be nice to just fly in to Montreal for lunch and fly back for dinner. What a snobby rich person thing to do that’d be.
