Definitely not worth the price of an international, business class ticket. I would advise you to choose a different carrier. Many of the Star Alliance members will match MileagePlus points as well, so don't let that be what stops you.
-Food was worse than may economy meals I've had.
-Service was not up to par with other business class experiences
I fly United domestically quite often for work, and it's a good airline.This review is only meant to express disappointment with business class on a long-haul flight. If you are going to spend the extra money (especially if you are flying business class as a once in a lifetime experience!!), you will have a much better overall experience on a different airline.
