Hi

Does anyone have any inputs to my predicament.

I have an existing fare booked in D. If i were to make flight time change online does it keep the original fare class, or will it automatically pick the lowest fare class available like what it does on their website.

I have a D fare booked, and there are P fares available on that day and would like to keep it at D. Am worried if i make the change online it'll change to the lowest which is P.
