Yes, you can still check-in at the airport in 2026, but it is increasingly becoming a paid or restricted service for many airlines. Most major "legacy" carriers like Delta or Emirates allow free airport check-in at kiosks or counters, but low-cost carriers (LCCs) like Ryanair, Frontier, or Spirit now charge "Airport Check-in Fees" that can range from $25 to $100 per person if you haven't checked in online beforehand. Furthermore, some "digital-first" airlines have removed traditional check-in desks entirely, requiring all passengers to use self-service kiosks unless they have complex document needs (like visas). If you have checked luggage, you usually do a "hybrid" check-in: you check-in on the app to get your boarding pass, then use a self-service machine at the airport to print your bag tags and drop them at an automated belt. To avoid unnecessary costs and long queues, checking in via the airline's mobile app 24 hours before your flight remains the gold standard.
