We made it back to Russia in one piece! The flight went pretty smooth once again. It wasn't the most comfortable sleeping arrangements on the plane but we knew what we were getting ourselves into--perhaps that was the problem. So it's 2:30am right now and Sydney and I are wide awake after sleeping for about 4 hours. At least I know we will adventually get back to a normal sleep pattern.
Same terminal as last time made it easy to locate the Wendy's.
