Porter Airlines always seems to be giving away great seat sales, but at this time of year with all the travel offers and high-demand for holiday seats its hard to tell which deals are actually ‘good’. In this offer from Porter, when you use the promo code, SP7WXA, and you book your seat for travel before January 7th, 2015 you can take 40% off of the base fare. At first, you may enter the dates for this an be shocked that all of the firm seats are gone, but with the 40% off discount it makes it so that the flexible tickets are about the same price as the regular firm fare.

Using this promo code, I was able to find a “last minute” round-trip ticket from Toronto’s Billy Bishop airport to Halifax for only $429.04 (taxes in). Initially, you may think that is a steep ticket price, but in comparison to the other airlines seats this was astronomically cheaper. On AirCanada, the same trip would have cost, at the cheapest option, $627.93; nearly $200 more!

Plus, by paying for the flexible pass from Porter Airlines for your return ticket, you will have the option to change your ticket at the last minute for only $50 versus the $75 it would cost for a firm fare ticket. This flexibility is really nice to have at this time of year when flying as the weather can change at a moment’s notice leaving you stranded and paying out your nose for a new ticket home.

This promo code from Porter Airlines is only available until tonight at midnight EST, and your travel dates must be between December 15th-January 7th, not including January 2nd – 4th.
