I have two reasons for flying with United. One is 3 years old and her baby brother is 5 months old. They live in Las Vegas, I split my time between Las Vegas and NJ and only United has daily non-stops between the two airports. Yes, the planes are not the cleanest, in general the food, when offered is inedible at best, upgrades are rare and after 28 years as an Elite/Premier they really don't care much about me because they know I will be back to see my grandchildren. One more point on clean planes, we now wipe our seats down before flying. Recently on a EWR-LAS trip we were in first, wiped the seats down and the wipes came out black. I sent a picture to United, maybe you got a response because I never did.......
