The glass viewing platform has been there ten years, and is one of the main attractions of the Arizona national park site. It is an exciting experience, but if you want to trod, look down a mile and smile into your selfie, be prepared to pay as much as $50 a walk and a peek.

Also, as with the famous canyon mule ride, you may have to buy your glass walking tickets months in advance. Since Skyrim opened, the average annual visitor numbers are close to a million. And it’s possible on the day of your visit, many of them will be in line ahead of you at the Skyrim. Anyhow, the price of entry into the park is just $25 per person, and there are many free spots to roam along the rims that offer views just as beautiful as on the Skyrim.

While ticket prices get larger, airlines are making seats smaller. In devious efforts to cram more paying butts on flights, the crafty engineers are making it more and more uncomfortable to fly.

There isn’t much senior fliers can do about it, but grin and squeeze in. If the cheap seat is too crowded and the flight isn’t sold out, ask the attendant to move you to a more comfy seat. Of course, if you have the dough, when you buy your ticket pay extra and sit in the overpriced section with the other snooty rich people.

Recently a commercial flight became frightful when the aircraft suddenly hit some heavy storm clouds. Passengers and loose articles went flying through the cabin. Several people were hurt. Such problems happen infrequently, but senior fliers should always be prepared for it.

Usually it’s only a slight rocking, giving passengers time to get ready. It’s the sudden unexpected shudders that often cause injuries. When it happens, even lightly, always anticipate it getting heaver. Stay in your seat and keep the belt fastened tightly. If you have dinner trays, cups and other loose items, secure them in the seat bag. Bundle up and keep hands, arms and legs close to your body. A bit of prayer may help ease your fears.

Lately, whenever I buy airline tickets, the rules seem to change. I always fly economy and over the years was permitted to take a small carry-on without extra charges. Now, many charge for carry-ons, and airlines keep adding fees to make flying more and more expensive. What can I do to keep my ticket prices down? Mrs. FLMcB, Quincy MA

A: The best way to keep up on extra charges is to connect with a local travel agent you can trust to find the best deals. Also, before buying your ticket, keep scanning the internet for seasonal specials and other airline price-reduction promotions. Also, to avoid checking suitcases, travel lighter with a small carry-on and wear a coat with large outer and inner pockets for stuffing as many items as possible.
