I'm considering confirming a Member Exclusive fare within Canada in Aug.on WS-operated flights but given the unpredictability of C-19 virus wondered about the flexibility of these fares so had some questions.

If Member Exclusive fares cannot be changed does that mean they are essentially Basic fares?

Can I cancel if I don't feel comfortable travelling and redeposit the WestJet Dollars back into my account? Is this is possible is there any deadline to do this i.e. up to 7-days prior to departure?

If I cancel would the tax paid be refundable?

Seats may be assigned at time of booking on Member Exclusive fares, correct?

I tried asking WS my questions however hold times are 3+ hours so since it's not urgent thought I would ask the experts on this forum for some insights.Thanks for any input.
