I applied for a claim to cancel my holiday, but only for half the cost (just the flight) due to medical reasons. I was asked to provide a letter from my GP, which I did, yet my claim was still rejected. The reason given was that the GP should have explicitly stated I was "not fit for travel," even though the letter detailed my illness and its cause. If a doctor confirms the illness, there should be no need for further confirmation regarding fitness to travel. I paid for the GP letter, but my case was still denied. This is extremely disappointing and feels unfair coming from Nationwide Travel Insurance. I have been paying monthly fees for years without making a claim, and now, when I need assistance, my claim is being rejected. Additionally, as Nationwide uses Aviva as a third-party insurer, it seems they are not handling claims fairly. I'm very unhappy with the way this has been managed.
