Thank all for the positive feedback.
Tute84: Tower no way... I know them and I rather stay away from them.
As I mentioned UAL and CO I have elite status (UA earned, and CO comped)
Ken: I have not used oneworld yet, specially because I have no elite there... I was going for the AA challenge program... but I gav e up and
Baobab: Good insight as well. my "orphan" miles were from years ago, when I was still a student and had "no idea" of ff programs.
However, after pan am went out of business, my miles went to delta, and I begun flying UA because I like them better than AA or RG for Brazilian flights.
Swissair is "new" to me, since I fly there once in a while and also use their MC partners.
As for "preffered airline" when I was working for Citibank, I "had" to fly AA, but I was able to get away and use a RG ticket flying UA.... and keeping my miles there.
Now, my situation will change, and I dont think the new employer has a policy on airline at all,...
again many thanks to all, and as soon as I know what my real plans will be and to where, I will post them...!!
