Is it a 777?

If so, sometimes 8A and 8B are blocked as crew rests and are only released closer to departure.

Latitudes.

For my part, I travel not to go anywhere, but to go. I travel for travel’s sake. The great affair is to move; to feel the needs and hitches of our life more nearly; to come down off this feather-bed of civilisation, and find the globe granite underfoot and strewn with cutting flints.
Robert Louis Stevenson (1850–1894)
