I understand that if the cost for my flight decreases, I can get a credit which can be used for a flight at a later date or for Baggage Fees. 1. Can I do this multiple times? (i.e. if the price drops and I get a credit, then it drops again, can I get an additional credit or is it a one time only credit)? 2. Do I have to call, or is there a way to get the credit by internet? 3. If I am purchasing one-way tickets for each leg of the trip (purchasing 2 sets of one-way tickets), will the credit apply to either leg (i.e. if the return leg price decreases, can the credit be used for baggage fees to Orlando)? Thanks.
