On Chase Sapphire cards you would be covered for non-refundable road trip charges (ie hotels, tours) if you were unable to make it to your destination due to things like weather delays or a family emergency / illness. Chase doesn't have a common carrier provision for their coverage - you just have to be 1+ mile away from home and charge a portion of the trip to the card.

Trip cancellation/interruption coverage is one of the areas I think having cards from both ecosystems works really well. I put all airfare on Platinum where the coverage includes the additional/alternate transportation coverage, and hotels and rental cars on Chase where coverage is enhanced (primary rental CDW) or more inclusive/less strict. Coincidentally this also aligns the charges to the card with the most favorable earning rates in those categories.
