Ariane Gorin
Chief Executive Officer at Expedia Group
Thanks,, and thank you all for joining us today. I want to start by welcoming Scott Schenkel as our new CFO. It's great to have him on-board, and you'll hear from him shortly. Our 4th-quarter results exceeded our expectations with room nights, gross bookings and revenue all growing double-digits. This top-line strength reflects our continued strong execution along with better-than-expected travel demand. Our disciplined cost management and top-line outperformance resulted in strong EBITDA growth with margin expansion.
Bookings for the consumer business accelerated for the third consecutive quarter to 9%, up 5 points sequentially. Each of our core brands, brand Expedia, hotels.com and saw bookings growth. Our B2B business had a stellar quarter with bookings growth increasing 5 points sequentially to 24%. And our advertising business posted yet another strong quarter with 25% revenue growth. Travel demand remained healthy in Q4 despite price increases in hotels, vacation rentals and air.
Like last quarter, international demand was stronger than the US with booked room nights growing high-single-digits in the US, low-double-digits in Europe and high-teens in the rest of the world. Our B2B business continues to benefit from this strong international demand, especially in APAC. And in our consumer business, our global expansion efforts continue to show solid progress with bookings growth outside the US accelerating 4 points sequentially.
Within our consumer business, Brand Expedia remains strong with Room Knights growing mid-teens. Air on Expedia notably improved, driven by higher-ticket prices, continued package product improvements and new merchandising capabilities. For hotels.com, bookings returned to slight growth driven by momentum in international markets. And for Vervo, bookings growth accelerated sequentially as well with improved traffic and conversion.
Global active membership in our loyalty program grew 7% in Q4 and our 12-month member repeat rate was also up over 300 basis-points year-over-year. Across our three core brands, nearly 50% of room nights came from silver, gold or platinum members. These higher-tier members receive additional benefits such as member discounts, which are funded by our supply partners and help to drive loyalty to our brands. Our strong 4th-quarter results contributed to a solid full-year 2024. When I stepped in as CEO last year, we set an ambition to bring and Hotels.com back to growth while extending our strengths in brand Expedia, B2B and advertising and being disciplined in our costs. While we have more work ahead, I'm proud of how our teams delivered against this call to action and built momentum over the course of the year. Bookings growth in our consumer business accelerated every quarter in 2024 from negative 3% in Q1 to 9% in Q4.
B2B bookings grew 21% for the full-year. We've grown bookings from existing partners through strong account management, great inventory and new product features and had our best year ever in-production from new partners. Overall, B2B accounted for 27% of our bookings last year and we've cemented our leadership year.
Our advertising business -- sorry, our advertising revenue grew 32% in 2024 and drove 5% of our overall revenue. We onboarded more advertisers to our platform, launched new ad types like video and introduced new tools for partners to manage their campaigns, all of which are resonating strongly with our advertisers. As a reminder, advertising is a high-margin, high-growth business and we see a lot more opportunity to innovate. Supply is at the heart of our business and we made great strides last year in improving our supply through technology investments, stronger partner relationships and everyday efforts from our commercial teams. We're sourcing more traveler benefits, whether through member deals or package discounts. We've released new functionality around merchandising and have improved the quality of our vacation rental supply. All of these are great for travelers while delivering valuable and targeted demand to our supply partners.
As we move into 2025, we have three overarching priorities, building on our progress from 2024. First, deliver more value for travelers. Second, invest where we see the greatest opportunity to drive growth in each part of our business. And third, continue driving operating efficiencies and expanding our margins. I'll share more color on each and then talk about how AI will help us across all three. Let's start with our first priority of delivering more value for travelers. Already today, we create effortless, personalized and rewarding experiences for customers. We do this through our supply, which deals travelers can only get through us and bundles and savings that we can uniquely create. We also do it through our industry-leading customer service and innovative products and features that travelers want. And in 2025, we're going to do even more.
In supply, more member rates beyond hotels and more targeted offers. In servicing, more self-service options both in the product flows and in the virtual agent experience. And of course, in-product, all powered by deep insights and data that enable personalized experiences that travelers trust. Moving next to our second priority, we'll invest where we see the greatest opportunity to drive growth in each part of our business. In our consumer business, this means focusing on our three biggest brands, having clear, sharp value propositions for each of them. For Expedia, for example, that's building on our strength as a one-stop shop and focusing on differentiators like packages while scaling newer products like vacation rentals.
Our consumer business is still heavily weighted to the US and while we made progress in 2024, looking ahead, we'll continue to push internationally in a targeted way. In our loyalty program and marketing, we'll be even more targeted in our spending. For example, looking deeply at where we see the biggest impact from our loyalty earn. And in B2B, it's about sourcing unique supply for our B2B partners, testing new products and signing new deals and deepening our commercial partnerships. And finally, our third priority is to continue driving operational efficiencies and expanding our margins.
We were disciplined in our cost management in 2024 and that allowed us to expand profit margins while reinvesting in strategic areas. We believe we still have room to deliver further efficiencies across our variable costs and fixed-cost base to expand our margins even farther. AI is an accelerator for all three of these priorities, and we've only scratched the surface. As we look-ahead, we're exploring the many ways AI will unlock even more value in our products. We're already seeing evidence of how AI is driving better experiences across the discovery, shopping and post-booking journey, which in-turn are driving loyalty and growth.
Going-forward, we'll continue to test and release AI-generated features to further personalize our traveler experience. AI also opens new possibilities to drive traffic to our brands as consumers increasingly search in new Gen AI native experiences and we're ensuring that we meet them where they are. And for our B2B business, the AI travel -- the AI-native travel start-ups that will inevitably emerge present new partnership opportunities for us. Finally, we see tremendous opportunity to use AI to allow our teams to move faster and be more productive. It's not just about cost-reduction. What's even more exciting is how it will enable our teams to spend more time where they can have the biggest impact. We're excited about the potential and are seeing early results across customer support, technology, marketing and our commercial teams, really across all parts of how we operate our business.
So in closing, we're pleased with our 4th-quarter performance and the momentum we've built over 2024. And we believe that in 2025 and beyond, we have a substantial opportunity to drive even greater value for our travelers, partners and shareholders.
With that, over to you, Scott.
