I recently stayed at the Sheraton Ontario Airport Hotel and had a wonderful experience. The hotel's location is incredibly convenient, being near the freeway and close to all the main areas, including shopping centers and the airport. This made arrivals and departures a breeze. The picturesque views from the hotel were quite relaxing and calming, adding a touch of serenity to my stay. The hotel itself was clean and well-maintained, with comfortable rooms and friendly staff who were always ready to assist. Overall, I highly recommend the Sheraton Ontario Airport Hotel for its convenience, beautiful views, and excellent service.

  • The early bird catches the most rewarding savings, so book your tickets the moment you know your travel dates. The cheapest airfares are quick to sell out and prices normally rise as the departure date gets closer.
  • Bundle your flights, hotels and car rental into a competitive package deal. Save your money for things you’re really excited about, like discovering every corner of Fort Irwin.

  • Whether you print it out at home or use an electronic one, you’ll need your boarding pass to step foot on the plane. You’ll also need some form of government-issued photo identification.
