About to purchase a set of B fares from PEK to EWR for late Dec/early Jan flight home. Wifey will be 30 and 32 weeks preggo on our flight home and return respectively. Looking at the rules and restrictions on the flights and they state: "FEE MAY BE WAIVED IN CASE OF ILLNESS OF
PASSENGER OR TRAVELING COMPANION OR DEATH OF
PSGR/IMMEDIATE FAMILY/TRAVELING COMPANION.
A VALID MEDICAL OR DEATH CERTIFICATE IS
REQUIRED."
If the wife isn't able to fly back to PEK due to her pregnancy would this qualify as a "case of illness"? And would my change fee also be waived?
