OTA (Online Travel Agency)
What is an OTA (Online Travel Agency)?
OTAs emerged in the late 1990s and fundamentally changed how consumers discover and purchase travel. Before their arrival, travelers relied on individual supplier websites or phone calls to travel agents. OTAs consolidated these fragmented options into searchable platforms that made price comparison effortless, catalyzing the evolution of online travel that reshaped the entire industry within a decade.
Today, OTAs represent one of the largest segments of the travel distribution landscape, alongside supplier-direct channels, global distribution systems (GDS), and travel management companies (TMCs) that serve corporate buyers.

OTAs function as intermediaries connecting travelers to suppliers without owning inventory themselves. They earn revenue through two primary business models:
Most major platforms use a hybrid approach, applying different models to different product categories or markets.
Behind the scenes, OTAs connect to supplier inventory through APIs, channel managers, and global distribution systems. When a traveler searches for a hotel in a specific city and date range, the OTA's booking engine queries connected inventory sources in real time, aggregates results, and displays options sorted by relevance, price, or user preference.
Why OTAs Fall Short for Corporate Travel
For business travelers, OTAs offer familiar convenience: broad inventory, price comparison, and self-service booking. However, corporate travel programs require capabilities that consumer OTAs were never designed to provide.
The GBTA Business Travel Index projects $1.57 trillion in global business travel spending for 2025 [2]. At this scale, unmanaged OTA bookings create significant blind spots for companies trying to control costs, protect travelers, and negotiate supplier contracts.
- Policy enforcement at the point of search (flagging or blocking out-of-policy options)
- Centralized invoicing and spend reporting across all travelers
- Duty-of-care tracking and emergency communication capabilities
- Pre-trip approval workflows
- Integrated corporate card management and automated reconciliation
- Consolidated data for supplier rate negotiations
Navan addresses this gap by aggregating multi-source inventory (including content from leading online travel agencies) while layering corporate controls, automated expense management, and 24/7 travel support on top.
OTA vs. TMC vs. OBT: Understanding the Differences
Travel managers evaluating booking solutions encounter three primary categories. Understanding the distinctions helps match the right tool to each scenario.
Feature | OTA (Consumer) | TMC | OBT (Corporate Booking Tool) |
|---|---|---|---|
Primary audience | Leisure and unmanaged travelers | Corporate travel programs | Corporate employees |
Policy enforcement | None | Integrated | Integrated |
Inventory source | Direct connections, GDS | GDS, direct, negotiated rates | GDS, direct, OTA content, negotiated |
Expense integration | None | Varies by provider | Built-in |
Duty of care | None | Full tracking and support | Full tracking and support |
Revenue model | Markup or commission from suppliers | Service or transaction fees | Subscription or per-booking fees |
Modern platforms increasingly blend these categories, combining TMC-level policy enforcement with OTA-caliber inventory breadth and consumer-grade booking interfaces.
When Should You Consider an OTA for Business Travel?
Not every business trip requires a fully managed platform. OTAs can be appropriate in specific scenarios:
- Unmanaged SMB travel: Companies with fewer than 50 employees and minimal travel volume may not need dedicated corporate tools.
- Personal extensions of business trips: When employees add leisure days onto work travel, OTAs provide flexibility outside corporate constraints.
- Rate benchmarking: Travel managers sometimes monitor OTA pricing to verify that negotiated corporate rates deliver genuine savings above publicly available options.
For organizations with meaningful travel spend, however, the lack of policy controls and consolidated reporting makes OTAs insufficient as a primary booking channel.
