I am going to Denver on Easter weekend April 14th - 16th. I have a denied boarding voucher and wanted to use it to bring a friend along with me. There is no availability for a return flight until Tuesday April 18th. If I book him on a return flight on April 18th can he go to the airport on the 16th and go standby? Since I will be travelling with him can I use my CP status to get him higher up on the standby list? Is this too risky to do on Easter weekend? Thanks!!
