The changes of insurance dates include change of effective date of the policy and change of policy period. Change of effective date of the policy: If a passenger decides to take another departure flight before taking the originally booked departure flight from China, the effective date of the policy will be changed accordingly, and the policy period will remain unchanged. Example: The passenger purchased a two-way air ticket (Shanghai to Hong Kong on January 6 and Hong Kong to Shanghai on January 9) as well as the two-way overseas travel insurance policy for 1 to 4 days. Now he decides to change his departure flight to January 7. The effective date of the policy will be changed to January 7, and the policy period (four-day period) will remain unchanged. Change of policy period: If the travel period of a passenger is extended or shortened for any reason, the Spring Airlines will not change the policy period. Example: The passenger purchased a two-way air ticket (Shanghai to Hong Kong on January 6 and Hong Kong to Shanghai on January 10) as well as the two-way overseas travel insurance policy for 1 to 4 days. Now he decides to change his return flight to January 11. The policy for 1 to 4 days will not be changed, and the policy period will remain unchanged (from January 6 to January 10). Note: The term “policy period” means the set of dates in which the policy is effective, i.e. 1 to 4 days, 5 to 8 days, and 9 to 14 days.
