January travel between Las Vegas (All Airports) (LASA) and George Bush Intercontinental Airport (IAH) is impacted by major events. CES (Consumer Electronics Show), typically held in early January in Las Vegas, drives up airfare and hotel prices; book early if traveling during show dates. Houston hosts the Houston Marathon in January, increasing demand for accommodations and some flights. Other local events include MLK Day commemorations and regional conferences. Plan travel outside peak event dates, or secure refundable fares and accommodations if you must travel during busy weekends.
The best time to fly LASA to IAH in January is midweek (Tuesday–Thursday), and during off-peak hours (early morning or late evening) to find the lowest fares and fewer crowds. Avoid the first week of January if traveling during CES in Las Vegas, when fares and airport wait times typically spike. If flexibility exists, aim for late-January dates after major conventions to capture deeper discounts. Use fare calendars and monitor airline sales for the best combination of price and schedule reliability.
