How to save money on a flight to Colorado

Getting some of the best deals on flights to Colorado is all about timing and flexibility. Here are some key tips to help you save:

1. Compare flight options—use Expedia's search tool to compare airlines, routes, direct vs. non-direct flights, and flight times. You can also sort by price to find the most affordable options.
2. Set up price alerts—stay up to date on fare changes by using Expedia's Price Tracker. Receive alerts when fares drop for your selected route.
3. Bundle and save—book a flight and unlock a hotel deal on Expedia*, or explore our Colorado hotel and flight deals.
4. Travel during shoulder season-peak travel periods tend to push the flight fares a little higher than usual. Traveling outside of these busy periods can help you find more competitive prices while still being able to enjoy good weather and lesser crowds.
5. Be flexible with your travel dates-if your schedule allows it, try and search for a few different departure and return dates as this may help you find lower fares.
6. Consider economy fares-if you're traveling light and don't need extras like seat selection or additional baggage, opting for a basic economy fare can be a simple way to keep costs down. Just make sure to check what's included in the flight ticket before confirming your booking.
7. Think about luggage—it's important to check the airline's baggage policies to find the best value. That may be paying for an additional carry-on bag or booking a ticket with checked luggage included. Either way, double-check your baggage allowance before confirming your booking to avoid excess baggage fees at the airport.
8. Earn miles—you can earn airline miles when you book with Expedia. Make sure to select your frequent flyer program and enter your program number when confirming your booking to get more value from your trip.

Tips for short-haul flights to Colorado

For quick getaways, efficiency is key. Here is how to make your short-haul journey smoother:

• Pack light and skip checked bags—with budget airlines, traveling with just a carry-on is often more affordable. Maximize space by using mini toiletries, wearing your heaviest clothing, and planning your outfits thoughtfully. This approach also helps you avoid waiting at baggage claim upon arrival.
• Early check in—nearly all airlines allow you to check in online at least 24 to 48 hours before your flight. This can save you time at the airport, and you may even secure a preferred seat without any additional fees.
• Bring your own entertainment—many short-haul flights might not provide in-flight entertainment. Download your favorite TV shows, movies, music, or podcasts in advance and consider bringing a book to keep yourself entertained. Make sure to fully charge your devices before boarding.
• Arrive early—Even for short flights, it's advisable to arrive at least 1.5–2 hours prior to departure, taking into account traffic and security lines.
• Bring your own snacks and water—pack some snacks and a refillable water bottle to stay hydrated and save money at the airport.

Tips for long-haul flights to Colorado

Flying long-haul sometimes requires extra planning to ensure a comfortable journey:

• Select your seat in advance—for longer flights, choosing your seat is crucial for comfort. Full-service airlines typically allow free seat selection once online check-in begins, which is generally 24 to 48 hours before your flight. Some airlines may permit seat selection earlier, but it could come with an additional fee.
• Arrive early—aim to reach the airport at least 3 hours before your departure for international flights to accommodate check-in, security, and immigration procedures.
• Relax at the airport—if you have some extra time, take the opportunity to explore the shops, find a coffee spot, or unwind at the gate or a departure lounge if you have access.
• Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone. Try to sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
• Dress comfortably—since the journey will be lengthy, opt for loose, comfortable clothing and layers, as cabin temperatures can fluctuate.
• Stay hydrated—bring along a refillable water bottle and make sure to drink plenty of water to keep yourself hydrated, ensuring you feel your best upon arrival.
