Traveling has become such a nightmare we no longer look forward to taking a trip. Nobody pays attention to where they’re walking because they’re texting. If our children know absolutely nothing about traveling politely, neither will their progeny. Are there any ground rules about the etiquette of travel?

–E.D., Boston, MA

When children see their parents constantly connected, it’s hard to put limits on texting, but I agree. It is difficult to navigate a car when you see people crossing intersections with their eyes glued to their device.

The good news is the trend that major cities such as New York — where on any given day six million people use the subway system — will soon be posting good etiquette posters in subways suggesting riders be considerate of space-related incursions: don’t block doors or hog poles, and carry backpacks in front instead of on their backs. Certain foods may be banned: no more eating messy, smelly food. No playing loud music, nor tending to personal grooming — including applying nail polish and deodorant, clipping nails, flossing teeth, and nose picking. Not hogging seats by spreading their legs in the shape of a V — a sore spot for busy travelers. Just ask them to move over when they’re taking up two seats. Riders should give up their seats for pregnant women and the elderly.

Watch, soon to follow we’ll be seeing etiquette posters in bus stops and airport terminals. Most suggestions are logical. Storing your carryon luggage in the overhead compartment putting the wheels in first to speed up the seating process making the compartments easier to use. When someone kicks the back of your seat, you feel what the person in front of you will experience if you kick his seat. Constant use of the reclining button can be annoying. If every traveler was considerate, traveling would be more so.
