Hey guys I have some specific questions about waitlists for award reservations: 1. Can you waitlist for flights that leave later in the day? (ex. I have a seat for a flight at 8pm but want a seat on the 10pm flight) 2. If I'm going to Asia via Europe on 2 segments, can I waitlist for a single CO flight crossing the Pacific? (ex. I have seats on EWR-LHR-NRT but waitlist for EWR-NRT) 3. Do alternate flight waitlists expire at T-24 like upgrade waitlists do? 4. If a waitlisted flight clears, do you have to do anything to accept the new flight? Will I have to pay change fees? (ex. $25 change fee as CO Gold for changes within 21 days?) Thanks in advance!
