I am currently booked business class award MUC-ORD LH434, which is a 340-600 departing 15:35. There is also availability on UA 907, which is a 340-600, departing at 12:35, either in business class or first class for an extra 17,500 miles. At those flight times, I'm probably not all that interested in sleeping. I have plenty of miles; that's not an issue. Firstly, which business class is a better product? Secondly, is it worth essentially $300+ to go first rather than business where it's unlikely I'll be doing all that much sleeping? Thanks for any assistance.
