When must blazers be worn by pilots?

Pilots are typically required to wear blazers from November 1 to April 30 due to the seasonal nature of this dress code, which aligns with colder months when formal attire is generally expected in professional environments. This timeframe encompasses the winter season, where blazers not only provide a polished appearance but also offer practicality against lower temperatures.

The specification allows airlines to maintain a consistent and professional image during periods when formal attire is deemed essential. This practice typically reflects the standards of various airlines and flight regulations that prioritize uniformity and professionalism in pilot attire. Therefore, wearing blazers during this designated period reinforces the disciplined environment of aviation and ensures that pilots present themselves appropriately to passengers.
