Actually I find United is still the best even post devaluation.
Used to be a Pan Am platinum and have done my share of travelling. At the moment all airlines are devaluing their programs.
At the moment my options besides Delta are BA, Etihad, Cathay, Jet airways, Thai and Singapore.
I am trying to avoid paying taxes on free tickets. I do that on lufthansa but the 50% companion award makes up for this.
Given my option of airlines I am wondering what to do.
