Summer vacation planning 2025 is over. Millions of families and friends planned vacations, researched destinations online, and booked flights, hotels, and tours through convenient, real-time booking services. Over 117 million Americans (44%) planned trips, spending an average of $3,861 each (totaling more than $452 billion) on airfare, lodging, dining, transportation, and activities. WebSitePulse's 2025 Vacation Planning Season Report is ready as well. For this purpose, we monitored 8 of the most popular international websites for travel and tourism during the vacation planning period between May 15th and June 30th, 2025.

For this Performance Report, WebSitePulse measured the performance of the websites' home pages and a complete web transaction like an end-user would interact with the website.

The report measured Uptime and Response Time as the most critical metrics for the availability and reliability of all web-based operations. Measurements of the multi-step online transactions are made every 15 minutes, simultaneously from 4 different monitoring locations: Washington, DC (US East Coast), San Francisco, CA (US West Coast), Sydney (Australia), and Amsterdam (Netherlands, Europe).

The overall performance of the monitored travel booking websites demonstrated their preparedness to meet the traffic during the whole 2025 vacation planning season.

We have found that the average daily response time from all monitored websites was 3,21 sec. (0.867 sec faster than last year's). The daily average response times by location are as follows:

• Washington, DC (US East Coast) – 2,609 sec
• San Francisco, CA (US West Coast) – 3,109 sec
• Sydney (Australia) – 4,380 sec
• Amsterdam (Netherlands, Europe) – 2,737 sec

For the fourth year in a row, the speed winner in this report is hotelplanner.com, with an average response time of 1.285 seconds, followed by lonelyplanet.com (2.581 sec) and bookaway.com (2.812 sec). Far away at the bottom of the table, once again, was hotels.com, with 5.151 seconds average response time, which may have caused some lost profit.

Compared to last year's performance, the three leaders decreased their response time by an average of 0.06 seconds, while the slowest site this year performed 2.224 seconds faster than in the 2024 vacation planning monitored period.

The daily average uptime for the entire group of 8 websites for the 2025 travel planning season was 99.91%. The daily average uptime by location is as follows:

• Washington, DC (US East Coast) – 99.91%
• San Francisco, CA (US West Coast) – 99.92%
• Sydney (Australia) – 99.91%
• Amsterdam (Netherlands, Europe) – 99.91%

This year's uptime winner, with 100% uptime, is hotels.com. At the bottom of the availability chart stands booking.com with 99.669%, which means it was not accessible to its customers for 3 hours and 44 minutes during the monitored period.

Methodology:
Performance and availability are measured for a typical travel-related booking web transaction at 15 minute monitoring interval, every day, 24/7. The WebSitePulse application monitoring service is used to collect data and to create the reports.
The steps in each transaction are comparable for all websites, and reflect the real online buyers' experience. The simultaneous monitoring is performed from four locations of the WebSitePulse global monitoring network: San Francisco, CA; Washington, DC; Sydney, Australia, and Amsterdam, Netherlands. In case of a detected malfunction or unavailability, the system performs automated error verification from four independent resources and only after the above procedure is performed and has returned consistent results, the detected error is confirmed, recorded, and included in the daily performance reports. In these cases, an advanced WebSitePulse exclusive feature comes into play - Forced Monitoring -, which automatically switches to a 3 minute monitoring interval for increased accuracy.

About WebSitePulse:
WebSitePulse is a leading provider of global, independent, and objective availability and performance monitoring of web sites, servers, network components, web applications, e-business- and email round-trip transactions.
