Had to cancel our trip to Scotland due to unanticipated need for spinal surgery, which was performed in August. Tauck was responsive and refunded the land portion cost within DAYS of cancellation. Aon continues to delay refunding the airfare portion and tells you it is busy with claims. Isn't it their business to have sufficient staff to process claims? Is paying claims a low priority so they can hold and use the money which should be refunded? IMO, Tauck needs to partner with a more responsive insurance company. Really, no excuse for these delays.
