I agree with you about not wanting to moan but think of it this way, when I fly on Jetblue I don't have a problem with the wifi. When I fly on Delta I don't have a problem with the wifi. Most of the time when I fly on AA I don't have a problem with the wifi. But whenever I fly with United I have a problem 50-75% of the time. To load an email and take a minute when it's just in HTML is unacceptable. If other airlines can get it right so can United, complain otherwise they don't know or think they are doing something wrong. (although I'm sure they are)
