Standby on award ticket
Currently booked out of DPS-SIN on KLM on an award ticket. My booking used a lot of miles for this flight (33K vs 12.5k) which might help with changing it? I'd like to fly the day before but its unavailable neither in J nor Y. I keep rechecking availablility and will do so until flight departure but could I possibly go to DPS airport on preferred departure date and get on standby? I don't mind paying a change fee because thats what an extra night hotel would cost anyway. Anyone have experience with this? I could call FB and ask them to recite me the rules but I'm looking for practical advice from other flyers. I'm Platnium for life, if that helps. Thanks!
