So we can book our airline tickets on June 4th. My mom is coming with us on this trip as well. My grandma has a ton of credit card points so offered to get her plane ticket for her but told me she couldn't book it till later in june. I'm going to call and check again on what the specifics are though. We would still get our tickets on the 4th when the booking window opens but my mom is afraid of waiting till she can get it with the credit card cause she is afraid that it will be sold out. What do you guys think? from your experience how quickly do flights book up?
