Do you have any tips for my flight to Innsbrook?

  • Wherever you’re going, flying can be a wonderful experience if you arrive prepared. First, pack your passport (or a valid ID), travel documents and medications. Next, throw in some extra in-flight entertainment to help make the time fly by. A juicy book and a tablet filled with your favorite series are good options. If you want to get some shut-eye, a quality neck pillow and noise-canceling headphones will also come in handy.
  • There’s a lengthy list of items you should not pack in your carry-on baggage too. Sharps, flammables and explosives are strictly prohibited in the cabin — they can include box cutters, razor blades, aerosol cans and flares. Some sporting equipment, like tennis rackets and baseball bats, also generally can’t go in your hand luggage. Visit your airline’s website for details about what you can and can’t take on board.

What to wear on a flight:

  • Opt for comfort before fashion when flying. Layer up and wear natural fabrics as they allow moisture and air to pass through and keep you cool. Cabin temperatures typically get cooler on long-haul flights, so pack a pullover and always wear sneakers or enclosed shoes.
  • The condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting caused by inactivity and poor circulation. Strolling up and down the aisle and doing foot and leg exercises while seated can help prevent this developing. Wearing compression tights or socks can also help to lessen your risk.

How can I get a cheap last-minute flight to Innsbrook?
If you want to nab a cheap last-minute flight to Innsbrook, being flexible is key. If you can, have a little wiggle room with your travel dates. It’s also a good idea to have a bit of flexibility with your departure and arrival airports, airline choice, flight times and potential stops or layovers.
Where can I learn more about changing or canceling my flight to Innsbrook?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
