Who was the actress who played the flight attendant in the movie in sarah marshall?

My friends and I noticed her and thought it was the women Catherine Keener (Trish) from the film 40 Year old Virgin. but there is nothing about her (or so it seems from my google searches) on the internet. either this women is a completely random person not worth crediting or it actually was her and she just didn't want the credit. i mean this was a small role and she does have four movies coming out next year. thanks
