ToolLast-minute flight booking is a gamble. Prices can be astronomical for popular routes or surprisingly cheap when airlines need to fill remaining seats. The key is searching broadly and quickly, because last-minute availability changes by the hour. Spending time checking sites one by one means prices may shift before you finish comparing.
The search_flights skill returns current availability and pricing for imminent travel dates across all carriers. You see which flights still have seats and at what price, letting you grab a deal before it disappears. This is valuable for emergency business trips, spontaneous weekend getaways, and situations where plans suddenly change and you need to rebook fast.
