The collapse of Spirit Airlines and rising fuel costs are pushing airfare higher just as Americans plan summer trips. The Memorial Day weekend travel surge will reveal whether households can absorb these climbing expenses.

Spirit's bankruptcy removes a major budget carrier from the market. For years, Spirit undercut competitors on price, offering fares that made flying accessible to cost-conscious travelers. With Spirit gone, fewer airlines compete on the lowest-price tier. Delta, Southwest, United, and American now face less pressure to discount aggressively. The result: fewer cheap flights available this summer.

Fuel prices drive the second pressure point. Jet fuel costs have risen sharply, and airlines pass these increases to passengers through base fares and fuel surcharges. A roundtrip flight that cost $250 six months ago may now run $320 or more.

These twin forces hit household budgets hard. A family of four planning a week-long beach vacation now budgets significantly more for flights alone. Budget airlines like Frontier and Allegiant remain, but they offer limited routes and impose strict baggage fees. Southwest continues its no-fees model, but prices have climbed there too.

Travel experts expect Memorial Day weekend bookings to signal summer demand. If tickets sell briskly despite higher prices, airlines will raise fares further. If bookings weaken, it means households are cutting vacation plans or driving instead of flying.

For your wallet, expect to pay more this summer. Book early if possible. Compare Southwest's all-in pricing against legacy carriers' base fares plus extras. Consider shoulder dates in late May or early June before peak summer rates kick in. Driving remains viable for trips under eight hours. Pack light to avoid baggage fees with budget carriers. Use airline credit cards strategically to offset fuel surcharges through rewards.

The summer travel season now rewards planning and flexibility over last-minute deals.
