Booking Holdings' stock rose nearly 8% in after-hours trading Monday after the company reported an 11% increase in revenue to $4.8 billion.

Net income increased 3% year over year to $1.8 billion. 

Gross travel bookings increased 12% to $24.3 billion. This quarter marks a milestone for the company with over 200 million room nights booked in the quarter, up 13% year over year, CEO Glenn Fogel said.

Late last month, Expedia Group's stock also surged following its earnings report, which reported a 10% increase in revenue.

On a call about Booking Holdings' quarterly results Monday afternoon, Fogel discussed the company's offerings in the realm of experiences and activities. 

"We're building out our product capabilities creating a seamless, integrated way to offer more choices for accommodations customers," he said.

In the past quarter, has made progress in integrating products from FareHarbor, the experiences booking software Booking Holdings acquired earlier this year, Fogel said. The company is also working to leverage FareHarbor's technology.

Experiences on are "scaling well," with activities in around 70 cities around the world, according to the CEO. Booking Holdings is also working on offering things like at-hotel services and restaurant booking options, though Fogel admitted those are "nascent efforts."

Responding to an investor's question about the importance of experiences during the call, Fogel said the area is a long-term play for Booking Holdings.

"In the long run it is important," he said. "It's not something we're just going to go a million miles an hour right now and crash the income statement by just throwing money at it, ... but it's something that is very, very important."

Experiences will bring in revenue but will also help make the travel experience easier for consumers. That, in turn, will build loyalty, the CEO said.

Fogel said he himself has used to book experiences and described it as "great."
