For those planning to stay connected or get some work done in the air, in-flight Wi-Fi costs can really add up, with airlines charging by the hour or offering any number of paid packages. Needless to say, having to shell out more for Wi-Fi during a flight can be a real pain for leisure travelers and quickly become a major expense for frequent business travelers.

Thankfully, there are a few ways to get around those extra fees, with more airlines offering passengers access to free Wi-Fi than ever before. Delta Air Lines announced that it will offer complimentary in-flight Wi-Fi for all customers — so long as they have a free Delta SkyMiles loyalty account — starting Feb. 1. Meanwhile, JetBlue has offered free high-speed Wi-Fi (via its Fly-Fi service) for years now and Hawaiian Airlines plans to introduce it later this year.

It turns out that there are other ways to dodge pesky Wi-Fi fees. Below, Select breaks down the best ways to avoid in-flight Wi-Fi costs on your next trip, whether by traveling with certain airlines, signing up for travel rewards credit cards that include it as a benefit, maintaining elite status, flying in premium classes or by simply having the right cell phone provider.

Domestic airlines

As mentioned above, Delta Air Lines now offers free in-flight Wi-Fi on most domestic aircraft and will offer it throughout its entire fleet, including international aircraft, by mid-2024. All you need to do is sign up for a free Delta SkyMiles account — if you don't have one already — then, once you're on board, simply log in with your SkyMiles number and password.

If you don't want to sign up for a SkyMiles account, you'll have to pay a $10 fee to access in-flight Wi-Fi, per device.

Otherwise, JetBlue is the only other U.S. carrier to offer complimentary Wi-Fi to all passengers on all its flights, regardless of loyalty program membership, status or route, via its Fly-Fi service. Hawaiian Airlines is also planning to launch free in-flight Wi-Fi in 2023 thanks to its partnership with SpaceX's SkyLink.

American Airlines also seems to be testing out free Wi-Fi on many of its aircraft that are equipped with Viasat — as part of an ongoing trial, passengers who opt to watch a sponsored video can access 30 minutes of Wi-Fi free of charge.

Other U.S.-based carriers, such as Alaska Airlines, United Airlines and Southwest Airlines let passengers send and receive messages for free via apps like WhatsApp and iMessage.1

It's also worth noting that United Airlines allows its MileagePlus loyalty program members to redeem 1,600 United miles instead of paying the usual $8 fee for in-flight Wi-Fi ($10 for non-members) on domestic and short-haul international routes to Canada and Mexico. While that's a poor value for your miles, i you've got some United miles to burn, it could be an easy way to get around paying extra fees to stay connected while you fly.

International airlines

As far as international airlines, Air New Zealand offers complimentary internet on all Wi-Fi-enabled flights, while Qantas offers it on select domestic flights. Nok Air, a low-cost carrier based in Thailand, also provides complimentary in-flight Wi-Fi aboard its Boeing 737 flights.

Some international carriers offer free Wi-Fi, but with certain stipulations. On China Eastern Airlines and its subsidiary Shanghai Airlines, for instance, a free in-flight Wi-Fi trial is only available to the first 100 passengers per flight who register up to 30 days in advance, while on short flights within Europe, aboard Norwegian Air's 737-800 aircraft, passengers receive 15 minutes of Wi-Fi for free.

Wi-Fi offerings vary greatly by the airline, flight path and the type of technology currently being offered by the carrier, so remember to check their website for the latest information before you set off.

Several airline credit cards offer statement credits meant to reimburse you for Wi-Fi charges made during flights with their associated carriers.

• Southwest® Rapid Rewards® Performance Business Credit Card: Reimbursement for up to 365 $8 in-flight Wi-Fi purchases on Southwest Airlines flights
• CitiBusiness® / AAdvantage® Platinum Select® Mastercard®: 25% back in the form of statement credits when you use your card to purchase Wi-Fi on American Airlines flights
• AAdvantage® Aviator® Red World Elite Mastercard®: Up to $25 back as statement credits on American Airlines Wi-Fi purchases each anniversary year
• United℠ Explorer Card, United Quest℠ Card and United℠ Business Card: 25% back in the form of statement credits when you purchase in-flight Wi-Fi on United Airlines flights
• Alaska Airlines Visa® credit card: 20% back in the form of statement credits when you purchase in-flight Wi-Fi on Alaska Airlines flights

Other travel rewards cards offer annual travel credits or airline fee credits that might cover in-flight expenses, such as Wi-Fi. The catch is that the transaction must be directly through the airline to qualify — charges by the internet provider itself, such as Gogo or Viasat, do not count.

• Chase Sapphire Reserve®: $300 worth of travel statement credits per year
• Hilton Honors American Express Aspire Card: $250 worth of airline fee statement credits per year for incidental in-flight purchases made with your preferred carrier
• The Platinum Card® from American Express: $200 worth of airline fee statement credits per year for incidental in-flight purchases made with your preferred carrier
• The Business Platinum Card® from American Express: $200 worth of airline fee statement credits per year for incidental in-flight purchases made with your preferred carrier
• Bank of America® Premium Rewards® credit card: $100 worth of airline incidental statement credits per year
• Bank of America® Premium Rewards Elite® credit card: $300 worth of airline incidental statement credits per year

Two important things to note: For the American Express cards listed above, you must choose a preferred airline each year and register in advance. For Bank of America's cards, only flights on U.S.-based carriers or trips that depart from the U.S. count when it comes to receiving airline fee credits.

If you happen to have elite status with carriers such as Southwest Airlines, Emirates, Icelandair, Singapore Airlines, Turkish Airlines or Scandinavian Airlines, among others, you can enjoy complimentary messaging or Wi-Fi access, though each airline has limits regarding time spent online, how much data you use and the number of devices, so check before you fly.

Alternatively, if you are able to book business or first-class flights when you're traveling internationally, that could be another way to avoid extra charges for in-flight Wi-Fi. Just be aware that how much free Wi-Fi you'll actually get and how many devices you're allowed to use varies greatly by the airline, fare class, flight length and current internet capabilities onboard the aircraft, so double-check ahead of time just in case.

If T-Mobile or Sprint is your current mobile phone carrier, you're in luck, especially if you've got an active Magenta MAX or Magenta plan. Those with Magenta MAX (or Sprint MAX, Unlimited Plus or Premium) plans can score unlimited in-flight text messaging, streaming and Wi-Fi on select Alaska Airlines, Delta Air Lines and American Airlines flights that offer Gogo in-flight internet service, and certain United Airlines aircraft equipped with Viasat or Thales technology.

Customers with Magenta, Simple Choice, Select Choice, ONE, T-Mobile pre-paid plans, as well as several Sprint plans — Sprint ONE, Unlimited Freedom, Everything Data Share, Sprint Unlimited, Affordable Choice and Unlimited Savings, among others — are eligible to receive complimentary in-flight texting as well as Wi-Fi and streaming on four flights per year, plus one hour of in-flight Wi-Fi and streaming on additional flights.

Either way, make sure your T-Mobile or Sprint phone is updated with the latest software, have a current e911 address listed on your account and make at least one Wi-Fi call with your SIM card before you go. Once onboard, ensure your phone is on airplane mode and that your Wi-Fi and Wi-Fi-enabled calling functions are turned on. Then, choose the airline's Wi-Fi network and log in on the Wi-Fi homepage using your T-Mobile or Sprint phone number.

While it may sound tempting to just fork over the $8 or $10 necessary to get your in-flight Wi-Fi fix, keep in mind that there are several things you can do to avoid those fees altogether. By opting for airlines such as JetBlue or Delta Air Lines that already offer complimentary Wi-Fi, using certain credit cards or cell phone carriers, flying in premium classes or maintaining elite status, you can easily wipe these charges from your travel budget and put that money toward your trip instead.

Before applying for a new credit card, remember to check your credit score, make sure you'll be able to use all the perks enough to justify paying the annual fee (especially if it's a higher one) and ensure you're able to meet any minimum-spending requirements for earning a welcome bonus responsibly.
