Bathrooms on 77A
One of the two bathrooms on the 77A appears quite a bit smaller, and seems to be used mainly by the crew.
The best part of the magnificent bathrooms on the 74A are the two windows in each bathroom. The bathroom on the 77A seems dingy by comparison.
Sadly, the days of the 74A to North America are numbered. The 77A will never come close to the luxury of the 74A.
