Timing plays an important part. Specifically, plane tickets usually don't get cheaper closer to the departure date. Instead, flights tend to be the most inexpensive when you book between four months and three weeks before your departure date.

Generally, no; United Airlines flights (like most major carriers) tend to increase in price as the departure date approaches. The "Goldilocks Window" for the cheapest fares on United is typically 1 to 3 months in advance for domestic flights and 2 to 8 months for international routes. Prices usually see a significant spike about 21 days before departure, followed by another sharp increase at the 14-day and 7-day marks, as airlines capitalize on "last-minute" business travelers who are less price-sensitive. While "last-minute deals" occasionally occur if a flight is significantly undersold, they are rare and unpredictable in 2026 due to advanced "Revenue Management" AI that optimizes seat availability. If you see a fare that fits your budget, it is almost always better to book it immediately rather than waiting for a price drop that may never happen. For the best value, use tools like "Google Flights" or the United app to set price alerts and track fluctuations during that optimal 1–3 month booking window.
