Do you have any tips for my flight to St. Helens?

  • Wherever you’re headed, flying can be a great experience if you’re prepared. Firstly, pack your travel documents, passport and medications. Next, toss in a little extra in-flight entertainment to while away the hours. A good read and a tablet filled with your favorite series are a couple of good options. If you plan on getting some sleep, a quality neck pillow and earplugs are also worth packing.
  • It also pays to check with your airline regarding what you can’t bring on board your flight. Batons, swords, box cutters, razor blades and knives are among the prohibited items. Anything flammable, sharp or explosive is generally not allowed in your carry-on baggage. Remember to pack any sports equipment like ski poles or baseball bats only in your checked luggage.

What to wear on a flight:

  • The aisles of an aircraft aren’t designed for a fashion parade. Layer up in comfortable, loose-fitting clothing and pack a hoodie since it can get cool in the cabin during long-haul flights. Closed-toe shoes are the best type of footwear for longer journeys.
  • Reduce your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for extended periods, by regularly walking around the cabin. Otherwise, do foot and leg exercises in your seat. If you’re at higher risk of developing DVT, think about wearing compression socks or tights.

How can I get a cheap last-minute flight to St. Helens?
If you want to grab a cheap last-minute flight to St. Helens, it’s important to be flexible. If you can, have a little wiggle room with the dates you plan to travel.
