Selective airline growth

Airlines usually pull back when fuel gets expensive. In April 2026, many are doing exactly that, with fare hikes, fee increases, and trimmed schedules spreading across the industry as jet fuel jumped from roughly $85 to $90 a barrel to as much as $150 to $200 in a matter of weeks. (zawya.com) Two carriers are moving the other way. WestJet and Brussels Airlines are both adding summer seats in 2026, but they are doing it on very specific routes where demand is holding up and the aircraft are already available. (newswire.ca) (press.brusselsairlines.com) WestJet’s expansion is aimed at the part of the market airlines call “sun” flying, which means vacation routes people book to get from colder cities to beach destinations. For summer 2026, WestJet Vacations said it is adding service from Canadian gateways to Mexico, the Caribbean, and Central America starting in early May. (newswire.ca) The route map shows how selective this growth is. From Toronto, WestJet highlighted daily flights to Cancún and Montego Bay, plus multiple weekly flights to Punta Cana, Puerto Plata, Sint Maarten, and Liberia in Costa Rica. (newswire.ca) From Calgary, WestJet said it will run daily service to Cancún and Puerto Vallarta, with multiple weekly departures to Los Cabos, Mazatlán, and Liberia. Mazatlán from Calgary is also being kept as a year-round service, which tells you the airline sees enough demand there to keep the plane moving even outside the peak season. (newswire.ca) This is not a broad bet on every market. It is closer to a grocery store giving more shelf space to the items that still sell fastest when costs rise: beach routes with proven demand, nonstop flying from large Canadian cities, and package vacations that can fill seats quickly. (newswire.ca) (zawya.com) Brussels Airlines is making a similar move inside Europe. On March 31, 2026, the Belgian carrier said it would add about 170 extra flights and 60,000 extra seats to its European network for July and August because demand for travel within Europe is rising. (press.brusselsairlines.com) The extra flights are concentrated on cities where summer demand is easy to picture. Brussels Airlines said Ljubljana and Bilbao each get three extra weekly flights, Prague and Alicante each get two, and Athens, Zadar, Faro, and Valencia each get one extra weekly frequency in July and August. (press.brusselsairlines.com) The reason Brussels Airlines can expand while others retrench is unusually concrete. The airline said new aircraft arrived sooner than expected, and weaker demand in the Middle East freed up capacity that could be shifted onto European leisure routes. (press.brusselsairlines.com) That detail matters because airline growth is often less about optimism than about aircraft placement. If a carrier suddenly has more planes than it needs on one part of the map, it will try to redeploy them to routes where people are still buying tickets at profitable prices. (press.brusselsairlines.com) (zawya.com) The contrast with the rest of the industry is sharp. Reuters reported on April 8 that Air New Zealand is cutting flights through May and June, Air France-KLM plans to raise long-haul fares by 50 euros per round trip, and American Airlines expects a $400 million increase in first-quarter fuel costs. (zawya.com) So the story is not that airlines suddenly stopped worrying about fuel. The story is that some carriers still see pockets of demand strong enough to justify more flying, especially on leisure routes to beaches or heavily booked summer cities, even while the wider market gets more cautious. (newswire.ca) (press.brusselsairlines.com) (zawya.com) For travelers, that creates a split market. On the routes WestJet and Brussels Airlines are targeting, extra seats can mean more choices and a better chance of finding a workable fare if you book early; on routes where fuel costs are forcing cuts, the same summer may bring fewer departures and higher prices.
