If I am trying to read, I do not like splotches of sunlight and shadow coming through the cabin windows onto my book. If we are flying from east to west, I like to plan to sit on the north side of the airplane while it is in flight. That would be the right side in the photo. Since Southwest has open seating rather than assigned seats, this is very much possible.
Step 1: Are We There Yet?
Most of my flights are only an hour or two in duration. But, we recently had a four hour flight from Nashville, Tennessee to Las Vegas, Nevada. Some pilots give the passengers frequent updates on where the plane is at the moment. Most do not. After a while, adults can be as curious as children to know where they are. Southwest Airlines gives small napkins with the snacks and beverages. The back of these napkins includes a nice map of the continental United States with cities served by Southwest neatly marked. Passengers can turn these into progress maps.
Step 2: Draw a Straight Line Between Cities
Step 3: Fold
Step 4: Sharp Crease
Step 5: Mid-point Mark
Step 6: Mark Quarter Way Indicators
Step 7: Fully Marked
It worked out neatly that we had a four hour flight. Suppose it had been a five hour flight. Each mark would represent 5/4, or 1.25 of the distance covered in one hour, or one hour and fifteen minutes. I could have made a notation by each mark: 1' 15", 2' 30", 3' 45", and 5'. Or, I could have converted that to real time. To be useful, that would mean factoring the difference in time zones between the city of origin and the city of the destination. In this case, Las Vegas (Pacific Time Zone) is two time zones away from Nashville (Central Time Zone). If we were due to land in Las Vegas at 2 PM local time, that would have meant a 9 AM Pacific take off in Nashville. I would have wanted to have changed the setting on my watch to Las Vegas time before taking off and before making my napkin calculations. My marks on the napkin would have indicated 10:15 AM, 11:30 AM, 12:45 PM, and a 2:00 PM arrival.
As of about 2012 Southwest Airlines offers WiFi on many of its aircraft. Above 10,000 feet in altitude devices which do not transmit or connect to cell phone towers may be used with the WiFi. A flight tracker is offered without paying the connections fee. A laptop or a Kindle will work, but a smart phone will not, not even on airplane mode. The image on a Kindle is grainy, but useful, and it gives other information about the flight (altitude, ground speed, estimated time of arrival, etc.)
Marking my napkin in this way did help me identify a couple of major rivers we overflew.
Step 8: What to Do in Four Hours
Step 9: Keeping Knees in Control
Assume the left side of the photo is on the aisle. I want to keep that knee from wandering into the aisle. I place that foot behind my other foot. Then I pull the foot in front back toward the seat. This hooks my leg in place and keeps my knee from wandering. Although it may not sound comfortable, it is and I sleep very well. Compare the photo in the previous step to see how much closer together my knees are in this photo.
Step 10: Using the Time
Many people use a laptop computer on an airplane. But, if the person ahead of you suddenly pitches his seat backward toward you because he wants a more relaxed position, his seatback can catch your laptop screen and break it. If I take a laptop on the plane, I do not often use it. First, the battery may not last the entire flight. Second, space is cramped and I do not want to risk damage to my screen. I prefer to think and make notes on a pad. When I am in an airport waiting for my next flight I can type the handwritten notes into the laptop. I can also use programs on my computer to generate more about which to think on the next leg of the trip.
Although it is now old technology, I really do like using my Palm organizer with a folding keyboard in place of a laptop. It synchronizes with my computer and allows me to compose or edit standard documents. If I am preparing a sermon, I can use a Bible loaded onto my Palm to find, copy, and paste references. The battery lasts and it is so small that I can use it on a seatback tray without danger of it being damaged.
I take an audio player with me and prefer earbuds as the best thing I have found for being heard over engine noise. But I do not often use them inflight because the volume must be quite high to be heard well, and I do not like to do that to my ears. Still, that is one thing can do for 20 or 30 minutes.
Reading the inflight magazine usually takes no longer than 30 minutes and is not a repeatable activity. The same can be said for consuming the inflight snack and beverage. I might sleep twice during a flight, but probably only once, at the best.
Occasionally, a seatmate is willing to converse, but that seems to be more rare all of the time. Sometimes I just think about some problem in my workshop that I would like to solve and make notes on it.
One good aspect of changing activities is that your mind can problem solve in the background while working on another activity.
Step 11: Directional Confusion
A finger works as an indicator. The watch must be set for the local standard (not daylight) time where the plane is at the moment. Point the hour hand toward the sun (yellow lines). Watch shadows across the aisle if you are not on the sunny side of the plane. Bisect the angle between the hour hand and 12 o'clock (red arrow). In the Northern Hemisphere, that line defines north to south, with north being opposite the sun, not toward it. Here is a more complete explanation for both hemispheres.
Step 12: Altitude Changes
Step 13: Setting Your Watch Accurately
You may have more and better tips for airline travel, but these have helped me a lot.
