I posted this on a seperate thread a few days ago but wanted to mention it here to make sure the Delta IT guys see it:
When I go to book JFK-GND I get to the final price confirmation screen and it asks me if I want to upgrade to Business Elite for $558...it even list all the benefits of the BE service with the seats and food/wine. This is obviously a huge error because BE service is not offered on JFK-GND on the 737.
