Yep, I tried at 5 am and got the lunch option for BOG, so I thought, what the heck, and tried to put it through but never got a confirmation page. For the heck of it, I tried again, and the time I requested the first time was not available, so I tried a reservation 5 minutes later than the first. All the way through... cc... yes, I understand... do I confirm. Yes, I do. They did not. So I tried a third time and this time I got a confirmation, Still nothing showing up so I could cancel or change, but I had the confirmation page captured, so was sure they wouldn't turn me away, Low and behold when I check my email this afternoon, ALL THREE CONFIRMATIONS (5 minutes apart) were there. It was my understanding that the system wouldn't let you book over other reservations, which is why I thought the first two had not gone through. Anyway, I just canceled a 12:30 for April 20th and a 2:15 for April 23.
