Just as a point of information, it seems like TAP is in more disarray than normal. I had a flight out of SdC to Lisbon on June 17th which got cancelled. On their website they show prices for flights in May and June of 2022 from SdC to Lisbon but when you try to actually pull up a week, all it says is no flights available. I can't believe they are pulling a connector flight like that but TAP is TAP. And as usually, their refund process is obscure. If you do get cancelled, make sure you use the link in the email to request a refund and NOT use the normal process on the website. The website link does not offer a refund (even if they cancel) - you get a voucher. The email link takes you to a different page which does allow you to request a refund rather than a voucher. But, then again, it's TAP so who knows what I'll get.
