One analysis showed that only 0.4% of London Heathrow’s total slots and 0.7% of Paris Charles de Gaulle’s were allocated to new entrants during the period under study.

Nov 21, 2020 JetBlue Lands Slots for London Expansion. Airlines must apply for takeoff and landing slots if they want to fly to London. Heathrow Airport, the region's primary airport, is the most extreme.

A landing slot, takeoff slot, or airport slot is a permission granted by the owner of an airport designated as Level 3 (Coordinated Airport), which allows the grantee to schedule a landing or departure at that airport during a specific time period.^[1] Slots may be administered by the operator of the airport or by a government aviation regulator such as the U.S. Federal Aviation Administration.^[2]

Landing slots are allocated in accordance with guidelines set down by the International Air Transport Association (IATA) Worldwide Airport Slots Group. All airports worldwide are categorized as either Level 1 (Non-Coordinated Airport), Level 2 (Schedules Facilitated Airport), or Level 3 (Coordinated Airport). At Level 2 airports, the principles governing slot allocation are less stringent; airlines periodically submit proposed schedules to the administrating authority, rather than historic performance. Participation is not mandatory, but reduces congestion and non-participants are penalized if the airport must later be designated level 3.^[2]

As of summer 2017, a total of 123 airports in the world are Level 2 airports, and 177 are Level 3 airports.^[3]

While IAG dominates with over 55% of all Heathrow slots and no other airline owns more than 5%, the rules governing slot allocation are currently under governmental review. “Heathrow has been dominated by one airline group for far too long,” said Shai Weiss, chief executive at Virgin Atlantic.
Nov 17, 2020 JetBlue Receives London Slot Allocation JetBlue applied for 1,302 new slots at Heathrow Airport beginning in 2021. However, none of the requested slots were allocated. This is not shocking though, as only 0.3% of the 43,043 new slot requests were fulfilled this time around.

Allocated landing slots may have a commercial value and can be traded between airlines. Continental Airlines paid US$209 million for four pairs of landing slots from GB Airways at London Heathrow Airport, $52.3m each.^[4] The highest price paid for a pair of take-off and landing slots at Heathrow Airport was $75m, paid by Oman Air to Air France–KLM for a prized early morning arrival, reported in February 2016. A year before, American Airlines paid $60m to Scandinavian Airlines.^[5]

As supply is limited, slot trading became the main solution to enter Heathrow and transfers grew from 42 in 2000 to 526 in 2012 and over 10 years the average priced slot was equivalent to £4 per passenger.^[7]

If an airline does not use an allocation of slots (typically 80% usage over six months), it can lose the rights. Airlines may operate ghost or empty flights to preserve slot allocations.^[8] To avoid pollution and financial losses caused by an excessive number of empty flights, these rules have occasionally been waived during periods of temporary but widespread travel disruption, including after the September 11, 2001 attacks, and during the SARS epidemic, the Great Recession, and the COVID-19 pandemic.^[9]
