I requalified for Platinum about a month ago, and since my company gets a big discount on UA flights,I though I would give it a try. I had been comped by UA to Premier Executive a few months ago, so I thought a comparison was in order. Other than the food being slightly better in coach (and that's not a fair comparision, since I have only flown CO coach twice this year)...there was not much good in being PE. So I board ahead of the masses, I do that in CO. At least at CO there is a chance of being ungraded--with no coupons or miles being deducted . On my UA flights I noticed a few empty seats in First--no FA came back to upgrade anyone . I think I will stick with CO.
