Take a vacation hold so you don't lose days, or gift remaining classes to a friend.
In the sidebar, tap My Passes. Each of your active passes has two new actions: Pause / Vacation hold and Gift classes.
Tap Pause, pick the last day you will be away, and confirm. Bookings are blocked through that day and open again the next day by themselves — there is nothing to press when you get back. Klasly pushes your pass expiry forward by the number of days you were paused, so you don't lose what you paid for.
Tap Gift classes, enter a friend's email, the number of classes to send, and an optional message. The classes are subtracted from your remaining count immediately so you can't double-spend. Gift classes appears on class packs and drop-ins that are still within their dates; a monthly pass doesn't have it, because its classes renew each month rather than carry over.
The recipient sees a Pending Gifts card at the top of their My Passes page with a Claim button. Clicking creates a fresh pass subscription with the gifted classes. They are good until the same last day as the pass they came from, and the gift has to be claimed by that day — after it, the gift is no longer offered. The recipient also gets an email saying who sent the classes and the day to claim them by.
