upgrade at check in
I did a search for this on the forum but didnt get anything. I have upgrade to first class before at the airport but do not remember the cost of economy vs first class. I had an economy ticket and upgraded to first class. I think I paid an extra $800 to $1000 for the upgrade, My question is has anyone else ever done this and got a better price because if the seats are available they want to fill them. Next time I will check how much the economy ticket is verses first class and see the difference at check in. I am also aware first class may not always be available. Has any one ever upgraded at the check in counter and got a better deal.
