ATN business class upgrade?

[captn337]

Does anyone know if ATN still offers business class upgrade on the day of the flight and what the cost is? How difficult is it to do this if it is offered? Thanks Ron

They do, but depending on when you are going, may be difficult to impossible to get. Business class was completely sold out ahead of time coming and going for us in Aug (we were booked in business and F, but I was going to surprise my son by upgrading him to business if it was available, which it wasn't).
