How do I claim for a refund of my airfare, If I am treated outside my country of residence?

The airfare is payable on a referral bases, that is, if treatment is not available in Guyana and is required overseas, a letter of referral from the physician must be submitted to Assuria. Airfare benefits are not applicable to vacations.
