Crowd-thrilling manoeuvres are expected at the Westport Airshow on Sunday.
Ground activity starts at 1.00pm, followed by the airshow over Westport's Quay at 3.00pm.
There will also be a fun fair, food and craft markets, live music, street theatre and face painting.
Visitors can experience the Wild Atlantic Way from the sky by taking a helicopter flight from Westport House.
Tom Gilligan is director of services at Mayo County Council: "To get the most out of the Westport Airshow we are encouraging visitors to arrive early and plan their trip in advance".
In conjunction with An Garda Síochána, there will be a traffic management plan in place which aims to minimise disruption to local residents, and get visitors in and out of Westport as quickly and safely as possible.
A number of road closures and traffic restrictions will be in place throughout the day.
However, all events and activities may be dependent on weather and are subject to change without notice.
