Hi there,

newbie here with question about rescheduling connecting flight. I'm going to Singapore from sfo, and if I buy a roundtrip ticket from sf to sg, can I reschedule the connecting flight going back home for about two weeks? The reason is that I would like to stay in HK for awhile before going back to sf. Any things to look out for? Will this affect my miles or impose additional fees? I will be buying the ticket from expedia. Thanks in advance
