Flights from IAH to DEN: Travel Guide & Ticket Tips

First and foremost, remember that Denver sits at over 5,000 feet above sea level, so staying hydrated during your IAH to DEN flight is crucial to prevent altitude sickness immediately upon arrival. Since Denver International Airport is located approximately 25 miles from the city center, consider taking the A-Line commuter rail, which is a cost-effective and efficient way to reach Union Station in about 37 minutes. For those flying out of Houston, always check which terminal your airline operates from, as IAH is massive and requires the Skyway or Subway for inter-terminal transfers. Lastly, if you are traveling during the winter months for a ski trip, ensure your sports equipment is packed in accordance with specific airline policies to avoid unexpected oversized baggage fees at the check-in counter.

Flight prices for the IAH to DEN route typically fluctuate based on the proximity to peak outdoor recreation seasons in the Rockies. Winters are generally the most expensive time to book, as skiers and snowboarders flock to the mountains for fresh powder, particularly during the December holidays and March spring break. Conversely, you can often find the most budget-friendly fares during the shoulder months of October and November or the mid-winter slump in late January.
