Firstly, you'll want some basic toiletries, such as deodorant, toothpaste and a toothbrush, a clean set of clothes and a good novel. Secondly, leave space in your bag for your electronic devices, chargers, any vital medications and perhaps a comfy neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel documents and some money. > > > Do not pack the following items in your hand luggage: > > > - Pack all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your treasured pocket knife, and products which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also prohibited. > > > What to wear on a flight: > > > - You'll want to choose comfort over style. Prepare for temperature changes in the cabin by layering up, and opt for flat, slightly roomy footwear like slip-ons. > - Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Denver? > - First things first. Your travel documents and passport will need to be inspected by airport security. Keep them someplace accessible so you don't hold up the queue. > - Next up is the X-ray machine. Remove anything metal on you that is likely to beep. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt. > - For just a few moments, you'll have to unplug from the digital world. Your phone, tablet and any other electronic devices will also need to go through the scanner. > - Travelling with a new cologne? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you in your carry-on luggage. > - There's a possibility that you'll be required to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a smart idea. > - Airlines will not allow any sharp items or pocket knives in your hand luggage. If you must bring these kinds of items, put them in your checked baggage. __Flights to Denver information__ | Destination airport | Philadelphia Intl. | | ----------------------------- | ------------------ | | Destination airport IATA code | PHL | | Destination city name | Philadelphia | | Return price | £445 | ## Trending flights to Denver Prices were available within the past 7 days and start at £325 for one-way flights and £446 for round trip, for the period specified.
