I've been invited to a wedding in Europe next summer. They are throwing in a First class flight from IAH on United to any European city and most any dates. Surfing around I see comments on how there are different Polaris qualities. Do I care? Then I see there is a Lufthansa 747 which may be a gold standard in service if memory serves me right. I don't fly much, so I'm curious what say others?
Take the Lufthansa or fly any first-class and relax, it's not that big a difference?
