Two years ago I flew FRA-ABV (Abuja, Nigeria) in C. I recognized the well-known evangelist Reinhardt Bonnke in F. He had an entourage of a few people flying with him, but they were in economy.
Eight days later I was returning from ABV to FRA, and once again, Reinhardt Bonnke was in F. This time I managed to get upgraded to F. We were the only two in the cabin. I chatted with him a bit. He's a very nice guy. I appreciate his message and integrity. I had taught a class of 50 people. He had talked to 50,000 people. Good for him. I wouldn't trade.
