What should a customer have to support their Trip Completion Expense Claim?

To support a Trip Completion Expense Claim, having documentation of failed travel services is essential because it serves as concrete evidence of the issues encountered during travel. This type of documentation might include receipts, emails, or written statements that detail the problems, such as canceled flights, missed connections, or unsatisfactory accommodations. Such evidence helps substantiate the claim by providing a clear context for the expenses incurred due to travel disruptions.

In contrast, proof of luxury expenses incurred may not be relevant to the claim unless they directly relate to the failed travel services. A letter from friends and family generally lacks the credibility and official nature required to support a claim, as it does not provide factual evidence of the expenses or disruptions. Lastly, while having all prior travel itineraries could provide background context, they do not directly support the assertion of incurred expenses due to service failures. Therefore, the only option that offers the necessary documentation for substantiating a Trip Completion Expense Claim is the one pertaining to failed travel services.
