Star Alliance Upgrades
Anyone had any experience (i.e. good luck)on long haul routes using the Star Alliance upgrades from any fare that came out recently to Star Alliance gold level members. I have a chance to use them on short haul in Europe but if people have had luck using them on Transatlantic and Australia routes on United (so I guess this doesn't apply to United members--I am Air Canada), I would be most interested and may save them for later this fall.
