Yes, you can ask for a first-class upgrade at the gate in 2026, but the likelihood of receiving it for free is near zero. Modern airline algorithms are extremely efficient at selling upgrades via apps or email bids days before departure. However, "gate upgrades" are often available for purchase at a discounted cash price if seats remain empty after all elite frequent flyers have been accommodated. If the flight is overbooked in economy, agents may look for "operational upgrades," but they will almost always prioritize passengers with high loyalty status. To maximize your chances, arrive early and politely ask the agent if there are any "last-minute purchase upgrades" available. Avoid asking for a "free" upgrade unless there is a significant issue with your original seat (like a broken seatbelt). In 2026, dressing well and being friendly still helps the interaction, but the gate agent's computer system usually dictates the upgrade list based on revenue and loyalty data, leaving little room for "manager's discretion" compared to previous decades.
