A study published on 2 April by Your Harlow, using Civil Aviation Authority Air Transport Movement statistics, ranks Southampton, Guernsey and Glasgow as the UK’s least reliable airports in 2025, with cancellation rates of 7.45 %, 5.35 % and 4.47 % respectively. By contrast, the nation’s busiest hub Heathrow cancelled just 0.97 % of its 40,294 scheduled movements. While the analysis looks backward, it lands at a moment when carriers are trimming 2026 schedules amid fuel and geopolitical shocks.

For business units suddenly juggling new routings, securing the right travel documents can be just as mission-critical as picking a reliable airport. VisaHQ’s UK portal (https://www.visahq.com/united-kingdom/) streamlines visa and passport processing with digital applications, live status tracking and expert review, ensuring that any last-minute shift from, say, Guernsey to Heathrow doesn’t trigger paperwork delays on the international leg.
Mobility planners often default to regional airports for cost or proximity reasons, but the figures suggest that hidden reliability premiums may outweigh headline fare savings. For example, a project team flying weekly via Southampton faces a one-in-13 chance of cancellation, potentially incurring hotel and productivity costs that dwarf the fare differential versus Gatwick (0.80 % cancellations). The data also underscore the resilience of London’s major airports, which delivered sub-1 % cancellation rates despite heavier traffic and last year’s Hayes-substation power outage. Practical take-away: incorporate historic on-time-performance metrics into travel-policy preferred-airport lists, especially for time-critical assignments. Relocation consultants may likewise wish to route home-finding or orientation visits through more reliable hubs even if ground-transfer times increase slightly. The CAA will release provisional 2026 figures in February next year, giving companies a chance to benchmark whether today’s high-cancellation airports improve after recent airline schedule rationalisations.
