✈️ 1. Airline Pricing is Dynamic
Airlines use real-time pricing algorithms that constantly adjust based on demand, availability, and user behavior. If you're viewing a fare and someone else books it right before you, the lower fare may disappear.
⏱️ 2. Delayed Price Refresh
Sometimes Skiplagged (or any travel site) shows prices cached from a recent search. When you click through to book, the system fetches the latest fare from the airline — and it may have changed.
📉 3. Limited Fare Classes
Airlines sell seats in fare "buckets" (like economy S, L, T, etc.). If only one seat was left in a cheaper bucket and someone else grabbed it, you're bumped to the next-highest price tier.
👀 4. High Search Volume
If a flight is being searched by many users at once — especially for popular dates or destinations — the system might raise prices to reflect increased demand.
🔍 5. Third-Party Redirects
When you're redirected to a partner site to complete the booking, that partner may not have access to the same inventory at the same price — especially if the fare is a special Skiplagged deal or hidden city ticket.
