For me a cold is a cold and I chose not to fly. I have one now and I am
dreading Thursday when I fly to the US for my holiday. 11 hours of flying
even as a passenger does not thrill me. I just know that pressure changes
will cause me sinus pain. It seems that anything involving more than 2000ft
in pressure changes with a cold becomes uncomfortable.

Try a double dose of pseudoephedrine hydrochloride (if it's available there).
Take it several hours before boarding and follow the directions for repeat doses
until you land. Its major side-effect is insomnia.
