- Morgan Stanley analysts favor Booking Holdings over Expedia in the online travel agency (OTA) sector, arguing Booking is better positioned as AI reshapes travel discovery and booking.
- The call centers on Booking’s larger direct-traffic base and brand strength, which analysts view as durable advantages when AI assistants and search intermediaries influence how travelers find and book.
- Expedia faces a harder path, with its reliance on performance marketing and paid channels seen as a vulnerability if AI platforms capture more of the top of the booking funnel.
- Both companies are investing heavily in AI features, but Morgan Stanley’s preference implies a relative valuation and share-gain gap between the two.
- The note reflects a broader debate over whether AI disintermediates OTAs or entrenches the largest platforms.
Morgan Stanley’s Core Argument
Morgan Stanley’s research team has staked out a clear preference in the online travel agency space, naming Booking Holdings as its top pick over rival Expedia. The reasoning rests less on near-term quarterly results than on structural positioning: how each company acquires customers, how much of its traffic arrives directly, and how resilient those advantages are if AI assistants become a primary interface for trip planning.
The bull case for Booking is straightforward. The company operates the largest accommodation marketplace globally, with deep inventory in Europe and a well-known brand that drives a substantial share of visitors directly to its apps and websites. Direct traffic matters enormously in this debate because it reduces dependence on paid search and other intermediaries. If consumers increasingly ask an AI assistant to plan a trip, the platforms with strong brands and loyal repeat users are better placed to be the endpoint of that journey rather than a supplier feeding someone else’s interface.
Why Expedia Faces a Tougher Setup
Expedia’s challenge, as Morgan Stanley frames it, is its heavier reliance on performance marketing and paid acquisition channels. That model has worked well historically, but it becomes more fragile if AI-driven discovery shifts where consumers begin their search. A meaningful portion of Expedia’s demand has come through channels where it competes on ad spend; if those channels change shape, the cost of maintaining visibility could rise.
That is not to say Expedia is standing still. The company has been rolling out AI-powered features across its brands, including conversational planning tools and smarter search, and it owns a portfolio that spans multiple travel categories. But scale in advertising and brand recall are difficult to build quickly, and Morgan Stanley’s note implies the market may be underappreciating the gap between the two companies’ structural advantages.
The AI Disintermediation Question
The central uncertainty hanging over the entire sector is whether AI makes OTAs more valuable or less. One view holds that AI assistants will aggregate options and push consumers toward the cheapest or most convenient supplier, squeezing intermediaries. The opposing view is that OTAs already solved the hard problems of inventory, payments, customer service, and supplier relationships, and that AI simply becomes another tool they use to convert demand more efficiently.
Booking’s scale gives it leverage with suppliers and a vast dataset of pricing and availability, which can feed recommendation systems. Expedia has similar capabilities but a smaller relative footprint in key markets. Morgan Stanley’s preference suggests the firm believes scale and direct relationships win in an AI-mediated world, rather than the technology flattening the field.
What to Watch
Investors will want to track direct-traffic mix, marketing efficiency, and any disclosure about AI-driven conversion in upcoming results from both companies. Commentary on how AI search and assistant partnerships affect customer acquisition costs will be especially telling. If Booking continues to grow direct bookings while holding marketing spend in check, the bull case strengthens. If Expedia can demonstrate improving organic reach and stable ad efficiency, the gap Morgan Stanley describes may narrow.
For now, the call is a relative one: Booking over Expedia, with AI as the lens rather than the catalyst. The sector remains sensitive to travel demand, consumer spending, and currency swings, and no single research note settles the longer-term question of who owns the traveler’s attention in an AI-first world.
