TUI is reviewing the capacity of TUIfly Belgium and considering a reduction in the number of aircraft based in the country. Group management has pointed to Belgium’s tax framework, including a planned rise in the air passenger duty on longer routes, as one factor in that review. The carrier currently bases around twenty aircraft and employs roughly two thousand people in Belgium. The group has already scaled back some Belgian operations in recent years, ending long-haul flying from Brussels, withdrawing from Lie ge and planning the closure of its Antwerp base. The latest review adds another layer: tax and levy costs are now part of the explicit calculation of where aircraft should live.
Fleet basing is never only about passenger demand. Aviation taxes, airport charges, crew social-security rules, carbon costs and the overall fiscal climate all affect the unit cost of an aircraft parked in a particular country. A higher departure tax raises the cost of every seat sold from that base. Differences in payroll and social charges alter the cost of crewing the same aircraft from one jurisdiction rather than another. Carbon and environmental levies add further variation. When margins are thin, even modest differences in these costs can tip the decision on whether the next aircraft is based in Belgium, the Netherlands, Germany or another TUI market. Aircraft are mobile; jobs and tax receipts follow them.
The same logic applies far beyond Europe. Indian states compete for airline and MRO investment through landing charges, fuel taxation and incentives. ASEAN markets differ in airport fees, labour costs and aviation taxes, a carrier choosing between bases in Thailand, Vietnam or Indonesia weighs those differences alongside demand. Gulf hubs have built part of their advantage on a combination of capacity, connectivity and a relatively competitive cost environment for long-haul operations. Policy choices that raise the cost of basing aircraft, whether through passenger taxes, social-security rules or carbon measures, can shift capacity and employment across borders even when underlying travel demand remains strong.
TUI’s Belgian review is therefore less a single-country story than a demonstration of how fiscal geography shapes airline geography. Governments that treat aviation taxes purely as revenue instruments may find that aircraft, routes and jobs move to jurisdictions that offer a more favourable total cost. The aircraft will still fly, they may simply be based somewhere else.
