At CLE this morning -- and a 737 with a UG list 43 deep -- "I'd next like to continue our pre boarding with 17 of United's most valued customers -- our 17 Premier 1Ks and their families are welcome to board. I'll be beginning Group boarding with Group 1 in just a few minutes...Premier 1Ks are welcome to preboard"
I thought it was a very nice and tactful way to handle it...
