Do you have any tips for my flight to Monarch?

  • Get your trip off to a wonderful start by being well prepared. Pack your passport or ID, travel documents and medications first. After that, consider downloading the latest movies on your tablet or phone for a guilt-free binge session. Or, toss in that fantasy bestseller you’ve been itching to read. Lastly, a few tasty snacks and a neck pillow will go a long way to making the flight as comfortable as possible.
  • There’s a lengthy list of items you should not pack in your carry-on baggage too. Flammables, explosives and sharps are strictly prohibited in the cabin — they can include knives of any sort, flares and aerosol cans. Some sporting equipment, like martial arts weapons and baseball bats, are also not allowed in your hand luggage. Your airline’s website will have a full list of what you can and can’t bring on board.

What to wear on a flight:

  • Whether traveling short or long-haul, layering up is key to flying comfortably. Choose loose, breathable fabrics that will keep you cool and bring a sweater for any in-flight cabin temperature changes. Your feet will be happy in a pair of flat shoes or sneakers.
  • Consider wearing compression socks or tights to reduce the risk of deep vein thrombosis (DVT). This condition is a result of blood clotting that can be caused by extended periods of sitting, especially on long journeys. Performing foot and leg exercises in your seat or walking around the cabin will help improve your circulation.

How can I get a cheap last-minute flight to Monarch?
Booking a cheap, spur-of-the-moment flight to Monarch is as easy as having some flexibility with your travel plans. Leave your options open with your choice of carrier, flight times and travel dates. If your destination has a few airports, compare the prices of jetting into each of them for the best deal on your airfare.
