Gatwick Airport has launched judicial review proceedings against the UK government's decision to relax airline take-off slot requirements, marking an unusual legal challenge from a major airport operator. The airport argues that the original rules requiring airlines to use eight out of every 10 slots were sufficient if properly enforced, and contends that the four-day consultation period showed the decision was prejudged.

Ministers introduced the relaxed measures in May to protect airlines from potential jet fuel shortages linked to the Iran crisis, dropping the usage requirement to seven out of 10 slots. Government officials expressed surprise at the legal challenge, with one calling it 'unbelievable' that anyone would question measures designed to support passengers and businesses during fuel disruptions. The move comes as airlines including British Airways have confirmed adequate fuel supplies for their summer schedules.

Airport industry body ACI Europe criticized the changes, warning they give airlines 'carte blanche' to cut services without delivering schedules. Airport slots represent significant commercial value, with carriers having previously flown empty planes to retain take-off rights worth millions. A judge will decide whether to suspend the rule changes while the case proceeds, with a decision expected imminently.

The legal action reflects tensions between airport operators and airlines over slot allocation policies, particularly as geopolitical tensions ease following the US-Iran ceasefire agreement.
