I’m not a fan of travel insurance for most trips. I think it’s overpriced, and often fails to deliver what consumers think they’re buying. The hassle in getting a claim covered can outweigh the value of the claim. To my mind it’s something to consider for a ‘trip of a lifetime’ where a loss really would be catastrophic (a trip that could never be replaced) but not for run of the mill travel.
That’s a different matter from making sure your health coverage extends to wherever you’re traveling and to medical evacuation coverage.
