Are you thinking of Flair or Swoop? Never flown them out of Kelowna when I was living there, but I remember both being a big deal when they finally arrived.
Swoop is owned by WestJet, it's just their discount brand. Flair's actually independent and used to be based in Kelowna but is now based in Edmonton – they're probably who GP is thinking of.
I'm incredibly thankful to Flair as my flight to Montreal now costs 1/3rd what it cost last year.
It's unfortunate that I need to visit a province that discriminates against my mother with its regressive laws, but at least I can pay my respects and get out without contributing to the oligopoly that runs the country.
