How to get the most out of in-flight Wi-Fi

Over the weekend, I discovered that my annual flight from Phoenix to Alabama (via Atlanta) had in-flight Wi-Fi. Best of all? It happened to be free, thanks to eBay jumping in on the free holiday Wi-Fi bandwagon. The promotion was already active on the flight I took from Phoenix to Atlanta. If you're traveling for Thanksgiving or Christmas, here's some things to consider about utilizing this service with your MacBook, MacBook Pro or MacBook Air.

Is it worth it?
It all depends. It was very nice being able to talk with my fiancé (who, on his part used FlightStats.com to inform me of where I was at) during the flight. I'm no fan of flying, and when the turbulence got bad, it was a nice distraction. However, I did notice I got a slight motion-induced headache and had to take a break. If the seat in front of you is reclined to the point where your computer is rammed into your chest, the person in the seat next to you is taking up half of yours with their elbows, or if you're inclined to motion sickness, this may not be for you. Still, a free promotion is the perfect time to give the service a try.

Normally, this service can cost anywhere from $6-15 for a flight. Gogo's pricing structure is $5.95 for a flight less than 90 minutes, $9.95 for a flight between 90 minutes and three hours, $12.95 for one more than three hours or a daily pass on a single airline. If you're just using your iPhone, it's $5.95 for a flight less than 90 minutes and $7.95 for one longer than that.

Read on for tips on maximizing your battery life in flight.

What to do before your flight
  • Charge your battery as much as possible. If this means rubbing elbows a family with seven kids or someone who's taking up three seats to access the only plug in the vicinity of your gate, then bite the bullet and do so. More airports are creating dedicated power stations for mobile users, but those tend to be crowded with those charging their cell phones. If you've got a mini-surge protector with USB ports in your carry-on, you can charge your iPhone or iPod at the same time as your Mac, while making friends with two other power-starved travelers.
  • Make sure your firmware is up to date. Apple's released a number of firmware updates over the years designed to tweak battery performance. Also, calibrate your battery if you have the time.
  • Transfer any media you plan to watch to your internal drive from external storage, if you normally keep it there (see below).
During the flight
  • Reduce monitor brightness. This is the single most important power saver you can implement on the fly. I find I can turn the brightness down next to nothing and can still view most things on my computer clearly. Even knocking the setting down to the halfway mark added a good 20-30 minutes to my battery life.
  • Turn off Bluetooth, unless you're using wireless headphones. Even though it's not going to cause navigational issues for your flight, it still chews up a little bit of battery power that you don't need to waste.
  • If you have an external drive, do not leave it hooked up to the laptop. Not only does transferring your movies and music to your internal drive save you some power, but some US airlines don't allow you to use outboard storage during flight.
  • Switch to integrated graphics, if available. Dual-GPU MacBook Pro models can save power (while giving up some performance on 3D applications) by moving to the lower-end graphics card; note that you do have to log out and back in to switch.
  • Don't use the illuminated keyboard, if your Mac is so equipped.
  • Quit any program you're not using. Don't keep your Mail application running, or if you do, set it to only check mail at certain intervals. If you're not watching a DVD, don't keep the player going. Same thing with iPhoto, iTunes, or any games you have installed. The more you're utilizing the CPU during your flight, the faster the battery depletes.
I began my flight with a 97% battery charge and ended at 33%. This mainly consisted of using iChat with the fiancé and using Safari to check e-mail, various forums, and reading through the archives of Girl Genius. Is this a service I would pay for? On a longer flight like this, absolutely.

Many thanks to fellow TUAW bloggers Aron and TJ for additional battery tips I didn't think of!

Most Delta flights have A/C outlet in between the seats so no need for an adapter, just plug in your normal charger cable.

I recently flew DEN-OMA for an evening flight on one of Southwest's WiFi-equipped planes (whole fleet will be sometime early next year, if I recall). I usually like to just look out the window when flying, as it's neat to see and helps me keep myself balanced during turns, but there is a lot less to see at night, so I paid the $4 or so and connected up my iPhone. It gives you ETA and altitude, and I believe a map too if you're on a laptop. Was able to email, tweet, and check Facebook perfectly well. I can see the valuie especially for longer flights.

If you have a Mac, you can set your Safari's User Agent to "iPhone" before you sign up for the WiFi, save a couple bucks, and then switch it back to normal once you've paid and you'll still be able to access the internet perfectly.

Good: In-flight Internet access.

Bad: In-flight voice access.

Pathetic: People who can't spent even a few hours apart without the need to be in constant electronic communication. It's bad enough having all the jackasses pop open their mobiles the moment a plane reaches the gate, thereby slowing down the process of gathering bags and getting the heck off the plane for everyone.

I tried in-airplane wifi for a recent flight from Atlanta to a northeastern US city on Delta. I didn't expect it to be usable, but much to my immense surprise, it was actually pretty good!

I used ssh to connect to my home server 3,000 miles away. Much to my immense surprise, according to traceroute, the latency was very low! Felt zippy. My connection was flaky for only a couple seconds during the entire flight.

Sadly, it was actually faster and a more pleasant experience ssh'ing at 37,000 feet in a metal tube at Mach 0.78 than when parked at a desk on the ground somewhere. I didn't do much web surfing so I don't know what graphics-intensive download speed was like.

Provider was AirCell -- via their GoGo WiFi service. Not all airplanes had it installed at the time but heard plan was to roll out fleetwide on more airlines and airplanes. Aside from Delta, United, American, AirTran, Air Canada, and Virgin America also uses GoGo.

I can't speak about flights out in the west or in the UK, but given the U.S. east coast population density, there's no shortage of cell towers and coverage. The wifi provider uses ground-based cellular tower connections to deliver the traffic.

I got a huge kick out of tracking my own flight in near-real time on flightaware.com, seeing the altitude, airspeed, heading, exact flight plan route, precip radar returns, etc.

The WiFi stuff works great with the iPhone, too. Airlines that uses GoGo has their route map for WiFi coverage shown at:

I recently used Delta's inflight wifi service on a flight back to Boise. I decided to stream some videos from Hulu, which worked surprisingly well for about the first 10 minutes. After 10 minutes however, the video stopped and I could hardly even browse the web. Any thoughts on why this happened? Do you think that they have a bandwidth cap, and that once you exceed it, your speed is throttled down?

Taylor,

Yes, they do have bandwidth caps; on AA's service they state that they will also do traffic shaping an prioritize things such as lower bandwidth HTTP over other UDP/TCP traffic such as gaming. They may be also shaping individual IP lease traffic, which would make sense.

So where in this article is Slim Battery Monitor mentioned? (Hint: you used the program's icon for the main story image)

Ah, remember the days when people got arrested for refusing to turn off their iPhones during flight because the plane would crash. "Oh, no, wait. I'm sorry sir, we've figured out a way to monetize your use now. Feel free. Go right ahead. Leave that phone on. Oh, but don't use external storage with your laptop because that in fact will crash the plane and release a plague upon the earth like never before seen."

Airlines - the only service industry where the customer is always wrong and you've got a US Marshal at your back, covering for your BS.

You seem to think that the airlines simply added routers to their aircraft. They had to add a crapload of shielding around every aircraft's avionics suite. And yes, the pilots can tell when you have your phone on. Ever heard the sound that a GSM phone makes to non-shielded speakers?

Perhaps I shouldn't have derailed the thread.

You seem to think that previously the avionics equipment sat in the middle of the aisle completely naked to incoming cosmic rays, the wifi from the airport itself, and a multitude of other potential sources of radio interference. What's your source for this "crapload" of additional shielding necessary to get wifi up and running? Is the equipment placed as far from the sensitive avionics equipment as is possible? Gimme some facts, not just guesses or anecdotal "evidence."

Yes, I've heard the results of interference on unshielded speakers. I've also heard the cessation of those sounds if the phone is moved more than two feet away.

I can't wait - I sure hope you're sitting next to me on my next flight to Phoenix.

I bet your seatmate was disappointed when you had to "take a break". What a shame for you that you couldn't talk through the whole flight!!!

I think (hope) that when she says talk she means chat. My understanding is they block voice services. I hope so.
