UK airline passengers are increasingly losing their booked seats due to a routine practice known as 'aircraft swaps' or 'equipment changes,' according to new analysis. Nearly 140,000 flights in the UK are affected each year, with airlines swapping aircraft shortly before departure to cut costs, address technical issues, or manage delays.
AirAdvisor, an air passenger rights company, reports that between 1% and 5% of flights face aircraft changes within 24-48 hours before departure, rising to over 5% during peak periods on legacy carriers like British Airways and Lufthansa. Low-cost carriers such as Ryanair and easyJet are less affected due to their standardised fleets, but summer demand spikes increase the risk across all airlines.
Passengers who lose a reserved seat or are downgraded may be entitled to compensation under UK261 regulations. Downgraded passengers can claim a refund of 30-75% of the ticket price, depending on flight length. Those who paid extra for a specific seat can claim a refund of that surcharge if the seat is no longer available. However, if no extra fee was paid, airlines can reassign seats within the same class without compensation.
Overbooking due to a smaller aircraft can lead to denied boarding, entitling passengers to compensation of €250-€600 (£216-£519), plus rerouting or a refund. However, there is no legal requirement for airlines to inform passengers of seat or aircraft changes, except when downgrading to a lower class. Consumer groups argue that airlines should notify passengers and provide automatic refunds when services are not delivered as promised.
The current review of UK261 regulations in Brussels has raised concerns that some proposals could weaken airlines' duty to compensate travellers for delays or cancellations. Meanwhile, the issue of aircraft substitutions remains largely overlooked in the talks, leaving British passengers increasingly at risk of finding out at the departure gate that their seat has vanished.
