Cheap Flights to Hawaii: How a Couple From Chicago Plans the Flights

A couple from Chicago can find cheap flights to Hawaii by fixing a flight budget first, searching a flexible window instead of one date, comparing every airline that flies the route, and booking only when a fare falls clearly below the usual price. This walk-through shows each step.

Hawaii has a reputation for being expensive, and the flight is only part of it. In a recent r/travel thread about a student trip, one commenter put it bluntly: "Hawaii is very expensive." So the flight is the one cost you can plan around, and that is what this post covers.

The trip

Maya and Daniel live in Chicago and want a week in Hawaii in the autumn, when they can take leave. They can leave any day in a three-week window, they fly from O'Hare (ORD), and they would rather fly midweek if it saves money. They have one fixed rule: the flights come out of a separate budget from the hotel and the car, so a cheap fare must not hide extra costs.

What they need

Two return tickets from Chicago to Honolulu (Oahu), with a carry-on each, at a total they set in advance. Their target is about $1,800 for both, which is their own planning number and not a price quote. They treat anything well below it as a good result and anything above it as a reason to wait.

Step by step

1. Set the budget and the window. They write down the target and the three-week window. A window is worth more than a date: it lets the search show them which days are cheaper.
2. Check a month view. In a flight search tool with a calendar or price graph they look at Chicago to Honolulu across the window. They note the cheapest days and how large the gap is. Often it is a few days that make the difference.
3. Add nearby airports. Chicago also has Midway (MDW). They check it too, and look at the fares from O'Hare on the airport page, so they see what a normal fare out of Chicago looks like. Fares to Hawaii depend on the route and season, so they only treat these as a baseline for the home airport.
4. Compare every airline on the route. One poster in r/travel compared Hawaiian Airlines with United for a trip to Kauai and said United prices had recently jumped while Hawaiian was in line with what they used to pay. Prices between airlines move independently, so Maya and Daniel check each one on their dates.
5. Add the real total. For each option they check the fare rules on the airline's own page: carry-on and checked bags, seat selection, and the cost of changing the flight. A low base fare with extras can lose to a slightly higher fare that includes them.
6. Try one-way tickets. They price the outbound and the return separately, because mixing two airlines can beat a single return on some dates.
7. Set an alert and let it run. Instead of searching every night, they sign up for alerts from Chicago. Cheap Flights Alert watches fares from the airport they choose and messages them when a fare is clearly cheaper than usual, on WhatsApp, Telegram or email. They also turn on price tracking in Google Flights for their exact dates, which emails them when the price changes significantly.
8. Book on a clear drop. When a fare falls well under their usual baseline and under their target, they open the link, check the final total with bags, and book with the airline or booking site.

What they end up with

Maya and Daniel end up with a flight plan, not a promised price. They know their window, their target of $1,800, and which airlines they have checked. They book when a total with carry-ons fits inside it.

The live data does not have a fare for a Chicago to Honolulu route to quote today, so this post gives no Hawaii price. For reference, the lowest fare Cheap Flights Alert had seen from Chicago O'Hare was $69 to Denver as of 2 November 2026, and the 30-day low was $68. That is a different route, so it says nothing about Hawaii prices. They check the real number on the day.

If the total ends up above their target, they have three options: move the dates by a few days, accept a connection, or wait and keep watching.

Where this falls short

• Alerts only fire when a fare is clearly cheaper than usual for the airport. If Hawaii fares are high all season, there may be nothing to send for a while.
• Cheap Flights Alert does not predict prices, so it cannot tell you whether to wait. It can only tell you when a fare is already cheap.
• It does not book flights, hotels or cars. The hotel, the car and the inter-island flights are separate searches.
• Prices change and sell out at any time. The final price is always the one on the booking site.
• A flexible window helps a lot, but school holidays or fixed leave can take that away. In that case compare airlines and book early enough to have choices.

A short checklist

• Decide the flight budget before you search.
• Use a window, not a date.
• Check at least two airlines and two airports.
• Compare the total with bags.
• Set alerts, and book on a clear drop.
