1936–1951
Founding wordmark
At its founding in 1936, Aer Lingus used a plain text logotype with no graphic symbol, consistent with airline identity conventions of the era. Early liveries were largely silver with minimal colour, reflecting both wartime material constraints and the modest scale of the operation.

1951–1965
Bold script era
The early 1950s brought a heavier, more confident typeface replacing the earlier lettering, paired with a shift away from red tones toward the green palette the airline would make its signature. This period coincided with Aer Lingus expanding transatlantic routes and acquiring larger aircraft.

This mark established the graphic language that would define Aer Lingus for decades.
1974–1996
King & Wetherell refresh
Designed by King & Wetherell
A comprehensive corporate identity introduced in November 1974 brought a new stylised shamrock, a richer deep green, and coordinated application across aircraft livery, uniforms, and signage. The programme was led by Arthur King, John Lister, and Martin Sampson at the London consultancy King & Wetherell.
1996–2019
Tilted shamrock
The 1996 revision softened the shamrock's colour, gave it a slight rightward lean, and added a stem, producing what press at the time nicknamed the 'drunken shamrock'. The accompanying wordmark used Friz Quadrata in modified form, giving the identity a more contemporary feel without departing from the established green palette.
2019–present · current
Lippincott redesign
Designed by Lippincott
Unveiled on 17 January 2019 and designed by Lippincott under lead designer Brendan Murphy, the current identity redraws the shamrock with heart-shaped leaves and a more pronounced tilt, rendered in a updated teal. The wordmark moved to the Diodrum typeface, and the full livery system places four shamrocks at distinct points on each aircraft.
