Livery: The "Bowling Shoe" livery features a red tail with a stylized 'N' logo (which also looks like an arrow pointing northwest), a grey fuselage section with "NORTHWEST" titles, and a deep blue pinstripe. This was the second of the airline's iconic red-tail liveries.
Identification: The number "300" is visible on the nose landing gear door of the aircraft, which is likely part of its registration or fleet number.
Historical Context: The A320 was the first entirely new aircraft type to join Northwest's fleet in 14 years when it began service in 1989. This particular livery was eventually replaced by the final "Silver" livery before Northwest merged with Delta Air Lines around 2008.
