Finding flights that work for you when there is a sweet promo code

So there is a promo code going around right now with Westjet for 25% off base fare for today only. Here is what I do to find the best deal.

  1. Check the details of the promotion: - Travel dates and blackouts - Cities - Other details as necessary

  2. Search for best dates on Google flights

  3. Go to and enter the promo code to get the 25% off the best date

So let’s take an example.

2. Search for the best dates on Google Flights

This is where the magic happens.

First we get the airport codes of the destinations on sale by entering the city names into Google Flights. We are then left with:

Caribbean: BGI, LIR, UVF
Europe: GLA

Then we pick 5 cities we would realistically like to go to and separate them with a comma. For me it would be: YHM,YQB,BNA,LIR,GLA

Now go to Google Flights. Enter the cities that you are realistically able to leave from. For me it is Victoria (YYJ) and Vancouver (YVR). Then enter those 5 cities you want to travel to.


Once we have the cities entered, we need to tell Google Flights that we only want to see results for Westjet flights. So select the “Airline” filter and scroll down to Westjet.

Now we can use Google Flights Calendar search to find the cheapest dates. Select the departure date and the calendar will pop up. Notice in green the lowest date is showing.

Once you select that green date it will come up with the flight details and the destination with the best price.

If you have strict times or layover requirements then you can use the filters to finetune your calendar search. ,

The main ones I like to play with are Stops, Departure/Arrival time, and Duration (under the More menu)

Then I click the calendar again to see what flights come up that suit my strict restrictions.

Low and behold there is one available. May 1st to the 4th.

3. Apply promo code on

Now I go to westjet’s website and I enter the origin and destination and also the specific dates from my search. Don’t forget to add the promo code!

Then I select the flights I like and see the price even cheaper as we used the promo code.

There you have it! It’s not amazing flight times but you understand the process and now you can search from your own home airport.

Don't forget to also check sites like NextDeparture as they have often done the hard work for you.

Happy flight searching!
