The Unite union confirmed ten-days worth of walkouts will go ahead at Heathrow from Friday (31 March) after talks to resolve a dispute over pay with the airport broke down.
But Advantage chief executive Julia Lo Bue-Said reassured that the majority of travellers will not experience delays as a result of contingency measures put in place to minimise disruption.
"However, we recommend travellers leave plenty of time to get to the airport and keep up to date on their flight time and any potential delays by checking the airline or departure schedule online," she added.
Lo Bue-Said reported the association’s Easter weekend bookings were up 6% after agents saw an uptick in demand for breaks over the four-day weekend (7 April) next week.
Stansted is expecting to see 175,000 people departing from the airport over the weekend and Manchester is expecting 300,000 passengers arriving and departing and will operate 1,904 flights over the four-day period.
The top five destinations Advantage members have seen are Lanzarote, Alicante, Majorca, Crete and Orlando.
"There is undeniably a huge appetite for travel this year, and the inclusion of the US in this suggests that people are continuing to prioritise travel despite the cost of living crisis," Lo Bue-Said added.
