I have multiple payment cards.
Card A has travel insurance coverage.
Card B does not have such coverage but has the convenience of holding multiple currencies in different accounts and switch to the right one automatically depending on where you pay (Revolut or similar). It has the advantage of minimizing the losses that happen during currency exchange.
In a recent situation, I paid for train tickets using card B. Then, I experienced a disruption during the said travel. Can I claim the incident on the travel insurance of card A?
