Wednesday night i checked in at UA for 1227 to DEN (at a kiosk)

i bought the tkt as "F" on a US flite number-6215- which was less than half the UA price for a "F" tkt

even thought i gave my premier executive number to the phone sales clerk at US, and also entered it on line, the kiosk did not show any number- so i entered it again

forgetting the fact that the weather was awful and we were delayed- beyond UA's hands- the miles and 150% bonus promptly posted to my account

so- i recommend you try the US codeshares- it seems to work- at half the price!
