Everything looked good, until I mentioned that I wanted to use $200 Gift Certificate and then pay the rest with credit card. The lady put me on hold, talked to her colleagues and then said I could not use GC because this flight was partially operated by another airline (part United, part Lufthansa). So I had to pay the full price (>$2k) with credit card.
My question is - Did anybody have the same trouble with them? Is it possible, for instance, to make them accept their GC and get a $200 refund to credit card? Or some other good suggestions?
To me this looks wrong - they already got money for the GC, and they don't let me pay with it? Makes it worthless in most cases for international travel.

P.S. I read Terms & Conditions - Valid for use on flights operated by United Airlines and United Express only - this does not say anything about booking, just using "on flights".
