Apple Pay support is still slowly rolling out from more banks, retailers, and apps, and two notable updates added Apple Pay in-app checkout options this week.

First up is Priceline, the app that aims to save you money on flights, hotels, and car rentals anytime you’re traveling. While the app allows you to book plane tickets and reserve rental cars, Apple Pay checkout is currently limited to “Express Deals” for paying for hotel reservations.

You still need to enter your booking information manually, but checkout is much easier now with Touch ID used to enter and confirm payments. Apple Pay through Priceline is available for iPhone 6, iPhone 6 Plus, iPad mini 3, and iPad Air 2.

Next up is MLB.com Ballpark, which was previously called MLB.com At the Ballpark, with support for using Apple Pay in the app at checkout. The faster payment option is limited to “select MLB Clubs only” when paying for single-game tickets for next year’s baseball season. You also still need to make an account with the app to view available tickets, but you may be lucky enough to see Apple Pay as a checkout option and be delighted if you happen to go to the right game.

In-person Apple Pay, of course, was supported at the stadiums during the World Series shortly after the mobile payment service debuted, and MasterCard took the opportunity to advertise Apple Pay and the iPhone 6 to promote that.
