Apple Watch on the road: The good, the bad, the odd

What works -- and what doesn't -- on the Apple Watch for road warriors

As I did with the Android Wear-powered Samsung Gear Live smartwatch, I've spent three weeks with the Apple Watch to see how it works in everyday business use. I found Android Wear to be all but useless and supremely annoying. The Apple Watch is a million times better, though it's more about convenience than strong utility -- a nice-to-have, not a must-have.

Still, if you're a road warrior, the Apple Watch can be useful ... except when its flaws get in the way. Here are the bumps in the road you can expect when using the Apple Watch while traveling, as well as some of the conveniences you'll appreciate when on the go.

Bad: Airplane Mode disables the Apple Watch

There's no option to turn off just the cellular radio, so your Apple Watch can continue to work in flight while you comply with airline rules on cellular access.

It's convenient to be able to set Airplane mode on your Apple Watch to enable it on your iPhone too. After all, your iPhone is probably in a pocket while you're in your airplane seat, which essentially imprisons you and limits your ability to move.

But the Apple Watch relies on Bluetooth and, to a lesser extent, Wi-Fi to communicate with the iPhone, which does most of the actual work you see on the Apple Watch. Enabling Airplane Mode disconnects the Apple Watch from the iPhone, suspending most of its features.

Nearly two years ago, U.S. and Europe regulators ended the ban on noncellular radio usage during flights, yet Airplane Mode continues to disable not only smartphones' cellular radios but also their Wi-Fi and Bluetooth radios. Yes, with an iPhone or cellular iPad you can turn Wi-Fi and Bluetooth back on -- but you can't do that from the Apple Watch.

Of course, the better approach is to redefine Airplane Mode to mean only cellular on/off, or provide a control in the Settings app to define what radios (in addition to cellular) that Airplane Mode controls. Alternatively, Apple can add a cellular on/off switch in the Settings glance on the Apple Watch and to the Control Center on the iPhone and cellular iPad.

Bad: Data detectors are not available on the Apple Watch

You can see where your next appointment is, but you can't tap it to get navigation directions.

OS X and iOS have long had a capability called data detectors that can identify physical addresses, phone numbers, email addresses, flight numbers, delivery services' tracking IDs, and calendar data (dates, times, and terms like "tomorrow"). If you click or tap such data, the operating system launches a compatible application to act on that data, such as to open the UPS tracking site or call a number.

But the Apple Watch doesn't support data detectors. (If it does, its apps don't.) That matters in travel apps like TripIt that show you, for example, your hotel reservation and address on your Apple Watch -- but doesn't let you act on them.

The Apple Watch does turn-by-turn navigation quite well, so as you navigate the airport, car rental lot, or city streets you know how to get your destination. But the Apple Watch can't get that data from your apps, so you need to go to your iPhone and use Apple Maps, Google Maps, Navigon, or your favorite maps app to begin that navigation. Or you need to memorize the address so that you can ask Siri on the Apple Watch to find that address and begin navigation.

Instead, you should be able to tap an address on the Apple Watch and have it launch Apple Maps navigation directly. But you can't.

Navigation is where road warriors will most notice the lack of data detectors, but the issue also comes up if you want to call the phone number for another item on your itinerary.

Bad: Boarding pass readers don't accommodate the Apple Watch

Apple Watch boarding pass

Having your boarding pass on your Apple Watch is quite convenient when your hands are full. The boarding-pass scanners at TSA security check-ins are open-face, so you can easily turn your wrist and place the Apple Watch screen on them. But the ones the airlines use at the gate are designed to read a paper pass slipped under the reader. The space is enough for a smartphone, so they can read Passbook boarding passes from your iPhone. But you can't fit your hand and wrist under the readers.

Thus, you need to pull out your iPhone to board the plane.

Good: You can easily see what seat you're in

When you're waiting in line in the jetway to board or as you enter the plane, you typically double-check your seat assignment. That's easy on the Apple Watch, from the Passbook app that stores your boarding pass. Simply scroll down to see what seat you're supposed to be in. (Tip: You don't need to find the app on your Apple Watch; swipe down to open the Notification Center, where your current pass will display. Then tap to open.)

Good: Pay for your meal from your Apple Watch

Some airlines are now supporting Apple Pay, such as JetBlue. Rather than dig around for your wallet to take out the credit or debit card, you can use your Apple Watch to buy your meal or drink -- and not have to fumble. If only that purchase were also stored in the airline app or Passbook so that you have a receipt ready for your expense report.

Good: You can manage your music from your Apple Watch

When I'm on a plane or train, I usually have my iPad out for work (like writing this post or updating my expense report) or entertain myself (say, reading books or watching movies). Unless I'm watching a movie, I also have my headphones on to listen to music from my iPhone, which long ago became my iPod.

When I hear the announcement tone for the airplane's PA system, I can easily pause the music from my Apple Watch, then resume it. I can also easily skip a song I don't want to hear. I can easily change the volume, which is very handy when I'm using headphones not equipped with a volume rocker. Sure, I could pull my iPhone from my shirt pocket to do this, but using the Apple Watch is easier in the confines of a coach seat.

Good: You can be sure to get up and stretch

Apple Watch Activity app

My instinct on a flight or train is to cocoon in my seat, but that's bad for my health. Deep vein thrombosis is the most serious risk, basically a clot caused by leaving your legs in the same sitting position for many hours, a poor posture encouraged by the pathetic space of airline (and some train) seats. But sitting for several hours is bad for your long-term health, even if you're not sitting long enough to risk deep vein thrombosis.

Apple CEO Tim Cook has said a mission he has for the Apple Watch is to encourage more physical activity, which our modern life has lessened. Thus, the Activity app is on by default on the Apple Watch, reminding you when you've sat too long or not moved enough. Yes, it can be annoying in a "don't bug me" way, but Activity is designed to stay on the right side of the nannyism divide.

On a flight, you'll get an hourly notice that you need to get up and stand for a bit. If you are in an aisle seat, there's no excuse not to comply -- except when the fasten-seatbelts sign is on, of course.

Odd: The Apple Watch's time zone updates as you are in flight

Apple Watch time zone

The Apple Watch changes time zones as you fly, with no indication unless you notice the offset in the World Clock app.

On my most recent flight, I glanced at my Apple Watch to see the time and noticed that the Calendar complication (what the Apple Watch calls an optional display field in an pop or glance) showed my flight schedule an hour later than its actual time. After poking around a few minutes, I realized the Apple Watch had adjusted the time zone from Pacific, where I started, to Mountain, to reflect my flight's current location.

Yet my iPhone and iPad still showed their times in the Pacific zone. And none of the devices knew where I was -- Maps couldn't determine my location because cellular was off and I was not using the airplane's Wi-Fi.

This mysterious incident prompted me to pay closer attention on my return flight later that week. Again, I turned off the cellular radio directly rather than use Airplane Mode so my Apple Watch would continue to work fully in flight. This time, I noticed my iPhone getting warm in my pocket, and when I checked it I saw the cellular status in the status bar at the top of the screen changing back and forth among "No Service," "Verizon," "Verizon 1x," "Extended," and "Extended 1x." There should have been no status at all.

That meant the cellular radio was operating, which would be be how the current time zone could be determined and made available to the Apple Watch. Although I had turned the Cellular switch to Off in the Settings app, the cellular radio clearly was still on. My subsequent tests showed that the Off setting was turning off the cellular data but not the cellular voice -- a violation of FAA regulations.

i assume this is a bug introduced with the iOS 8.3 update released in April, ahead of the Apple Watch's release. (I suspect the flaw is in iOS 8.3 rather than the Apple Watch OS because when I unpaired the Apple Watch and shut down and restarted the iPhone, the iPhone's cellular radio still did not turn off for voice, just data.)
