Do you have any tips for my flight to Oceanside?

  • Get your trip off to a great start by being 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 sans-guilt binge session. Or, throw in that thrilling bestseller you’ve been itching to read. Lastly, something to nibble on and a quality neck pillow will help make the flight as comfy as possible.
  • There’s a lengthy list of items you shouldn’t pack in your carry-on too. Explosives, sharps and flammables are strictly prohibited in the cabin — they often include knives of any sort, flares and aerosol cans. Some sporting equipment, like baseball bats and martial arts weapons, are also not allowed in your hand luggage. Check your airline’s website for details about what you can and can’t take on board.

What to wear on a flight:

  • The aisles of a plane aren’t suitable for a fashion show. Layer up in comfortable clothes and pack a sweater since it can get cool in the cabin during long-haul flights. Sneakers or enclosed, flat shoes are perfect for longer journeys.
  • Reduce your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for lengthy periods, by regularly walking around the cabin. You can also do some gentle lower limb 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 Oceanside?
To pick up a cheap last-minute flight to Oceanside, flexibility is key. If possible, have a little wiggle room with the dates you can fly. It’s also a good idea to leave your options open with your departure and arrival airports, choice of carrier, flight times and stops or layovers.
Where can I learn more about changing or canceling my flight to Oceanside?
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.
