Travelsphere and Just You are offering customers a £100 discount if they make their own travel arrangements to and from the airport.
The sister escorted touring specialist operators say the move adds an extra layer of flexibility that they hope will encourage bookings during peaks.
All tours still include return flights, accommodation and a tour manager.
Sarah Weetman, head of sales at parent company G Touring, said: “Our customers already enjoy an unrivalled choice of either our uniquely personal Private Chauffeur Service or free airport car parking included in our holidays.
“A consequence of the pandemic is that customers want even more flexibility and control to customise their holiday.
“To many this starts with how they travel to and from the airport, and some customers wish to make their own arrangements.
“We’re therefore introducing £100 price reduction when they make their own arrangements.”
Travelsphere and Just You will continue offer deposits of £21 and a 21% discount on holiday insurance, both initiatives introduced last year.
The operators’ Flexibility Promise has also been extended. It allows customers to change or amend bookings as many times as they want without fees until 75 days before departure or until February 28, 2022, whichever date comes first.
