Maybe get the choice above the cheapest option because you don't get a checked bag or carry on so in the end you end up paying about the same, if not more.

I would recommend Westjet. I suggest checking in at the agent counter. My husband & I don't mind sitting apart on a short flight rather than paying to sit together, but the agent was able to get us seats together. I did think the prices for selected seats was reasonable. Baggage fees were confusing & a bit pricy, but carry-ons were free & plane had large overhead bins.
