According to Qatar Airways' cancellation policy, if a traveller is unable to take a trip due to a serious illness that affects either the traveller or a close relative, the traveller may be eligible to guarantee a refund after presenting a medical certificate in accordance with Qatar Airlines' general preference. As long as your departure date is less than seven days away, Qatar Airways' cancellation policy for flights to or from the United States allows you to hold your reservation without paying for up to 24 hours. The regular rules of your fare will be enforced if you pay for and accept your ticket before the 24-hour period has passed.
