For cruising altitudes, which parity is used when flying Southwest?

The cruising altitude system in North American airspace is based on direction to keep traffic separated on the same routes. Eastbound and northbound flights use odd thousands plus 500 feet, while westbound and southbound flights use even thousands plus 500 feet. Since Southwest often operates westbound routes across the continental U.S., the cruising altitudes are assigned in even thousands plus 500 feet (for example, 6,500 or 8,500). So, the best answer is that even parity is used.
