I have ticketed a one-way award reservation from CUZ-LIM, booked with British Airways Avios award points. My flight departs at 15:30, it was the best time for me available at the time of booking. Now, I see that an award option is available for the 15:25 flight, which was not available at time of booking. I know that 5 min. is not much, but if possible, I'd like to be on that 15:25 flight. If I were to go to the BA website to change my ticket, they want $80 for the two of us traveling. I realize that $80 may not be bad as US airlines would charge up to $300 for two passengers for changes. Nevertheless, I'd rather not pay at all.

So I was wondering, at check-in in CUZ, if seats are available on that 15:25 flight, could I ask to be changed to that flight without any kind of extra charges? There was once a time not too long ago in the US where same day changes at the airport did not incur any fees, if seats were available. Those times are now gone, but I was wondering how things might work with LAN.

Thank you for your replies.
