Frequent fliers tend to have their favorite perks, like access to airline lounges, early boarding or free upgrades to the front of the plane. Pat Shanahan, a marketing consultant in the seafood and agriculture industries, said she most values the Alaska M.V.P. Gold benefit of being able to change plans without a ticket change fee. It saves money, she said, when clients change meeting plans, and the extension will help keep business costs down when she can travel again.

Major hotel companies are also ensuring their most valuable customers keep their perks. Hilton Honors elite status is extended through March 2022; Marriott Bonvoy through February 2022; and World of Hyatt’s tier membership is extended through February 2022. The companies are also delaying the expiration of earned rewards — like suite upgrades, club access and free-night certificates — to the end of 2021.

Hotels base status on stays and spending and also reward top customers significantly more than lower-status guests, Mr. Ewen of The Points Guy said. But the difference in hotel benefits is not “as glaring” as those offered by airlines because the hotels have a smaller range of experiences to offer. “You can upgrade a hotel guest, but there isn’t much difference between the bed in the presidential suite and the bed in a regular room, compared to the difference between an economy seat to Tokyo versus business class,” he said.

For those that don’t travel as often, Hyatt, Hilton and Marriott have all suspended their policies of points expiring when an account has been inactive for a period of time.

While changes in hotel loyalty programs are generally straightforward, airline programs are more byzantine and in some cases, changes vary at different levels, so travelers should read the website fine print.
