Hawaii on Sale! East Coast Cities $534 RT, Dallas $484 RT, Travel Aug. through Dec.

Here's another round of those wonderful unadvertised sales to Hawaii that have been showing up by surprise every now and again. This time around it is from United Airlines (with a couple of fares from American), who are offering discount deals to four different Hawaiian Islands. These deals are available from August 28 through December 25, with departures needing to take place by early December. In most cases, these fares are available daily, but certain routes may require a long layover. You can click on the fares below for specific details on each route. All these fares book into regular economy, so you will be allowed your regular sized carry-on to take onboard.

Since this sale is unadvertised, it may disappear at any moment. If any of these routes catch your eye, we recommend booking ASAP. United Airlines will allow you to cancel free within 24 hours or put an itinerary on hold for an extended period for a small fee with its FareLock feature. If you are on the fence about booking, it's better to reserve something now and think it over.
