Frequently asked questions

How to book the cheapest flight to Frontier?
If you want to save some cash on your trip to Frontier, listen up! As every seasoned jet-setter will tell you, don't book at the very last minute. Fares are often highest just prior to the departure date. Don't stop there, however. Do some research and check if there are a couple of airports at your destination. Fares often differ depending on the airport you fly into. Remember to compare prices across airlines as well. Lastly, be ready to lock in your seat quickly if you stumble on a great deal. It might not stick around for too long. With a bit of knowledge and a little luck, the perfect fare can be yours.
Do you have any tips for my flight to Frontier?
We've got the lowdown on how to make your flight as pain-free as possible. Follow our tips and tricks and you'll be zooming through the airport and exploring Frontier before you know it. What to pack in your hand luggage:

  • The trick to having an awesome travel experience is to pack in advance. Start with the essentials: passport, official ID, credit cards and any vital medications. Next, bring on board items that'll help keep you entertained, like some electronic devices or a few magazines. It's also a wise idea to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. And of course, be sure to chuck in toiletries like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a pocket knife) lurking in one of the zippers of your carry-on luggage. Other prohibited items include flammable or explosive products, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your aim is to feel as comfortable as you can. Pick shoes that are easy to pull on and off, dress in loose, natural fibers and remember to bring a pullover in case it gets chilly in the cabin.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Reduce the risks by drinking water, keeping your feet and legs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Frontier?
The trick is to be well organised before you arrive at the security gate. That way, you'll be hopping onto that plane to Frontier in no time at all. Follow these helpful tips and get your holiday off to a flying start:

  • Keep your ID and boarding pass easily accessible. They'll be the first things you'll be asked to show at security.
  • Time to strip down. Well kind of. Your belt, coat, keys and other small items, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • Your electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry, you'll be back online soon enough.
  • Any gels or liquids, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Hiking boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed on board and will be confiscated.
