Over the past week, I've noticed that DL has increased the number of flights from MSP to PHX. They're popping off six A333's a day right now.
Commercial aircraft flown in: B712 B722 B732 B734 B737 B738 B741 B742 B744 B752 B753 B762 B772 A310 A318 A319 A320 A321 DC91 DC93 DC94 DC1030 DC1040 F100 MD82 MD83 A223 CR2 CR7 E175
