Misunderstanding a convention schedule - it starts on the 15th in the evening, not the day thereof, yes, that means the 15th but not how I'd thought - means calling customer service to see if I can change the flight. In the past, it'd have involved an actual person as a travel agent. In the present, it means putting my phone on speaker and passing the time browsing the internet.
