The vacation planning season is now over. The last year was a rough season due to coronavirus (COVID-19) traveling restrictions. However, this year people were allowed to move freely across the country and abroad.

Summer vacation spending in 2021 was predicted to be record-breaking, according to Allianz Partners USA's 13th annual Vacation Confidence Index. Americans' total summer vacation spending should be around $153.7 billion this year - a 160% increase over 2020 and a 50% increase over 2019.

Our 2021 Vacation Planning Season Report is ready as well. For its purpose, we at WebSitePulse have monitored 10 of the most popular international websites for travel and tourism during the vacation planning period between May 18th and July 4th, 2021.

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 the 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 2021 vacation planning season. We have found that the daily average response time from all monitored websites was 5.844 sec. (1.066 sec slower last year's). The daily average responses by locations are as follow:

• Washington DC (US East Coast) – 3.757 sec
• San Francisco, CA (US West Coast) – 5.077 sec
• Sydney (Australia) – 9.645 sec
• Amsterdam (Netherlands, Europe) – 4.852 sec

For the second year in a row, the winner in this year's report is hostelworld.com, with an average response time of 2.547 seconds, followed by airbnb.com (2.964 sec) and vrbo.com (3.272 sec). Once again, far away at the bottom of the table was hotels.com with 11.479 seconds average response time, which may have caused some lost profit.

Comparing to the last year's performance, the three leaders improved their response time by an average of 0.017 seconds, while the slowest site this year performed on average 3.169 seconds slower than in the 2020 vacation planning monitored period.

The daily average uptime for the entire group of 10 websites for the 2021 travel planning season was 99.92%. The daily average uptime by location are as follow:

• Washington DC (US East Coast) – 99.93%
• San Francisco, CA (US West Coast) – 99.93%
• Sydney (Australia) – 99.91%
• Amsterdam (Netherlands, Europe) – 99.92%

The winner with 99.998% is booking.com, followed by edreams.com (99.994%) and tripadvisor.com (99.993%). At the bottom of the availability chart stands hostelworld.com with 99.705%, which means it was not accessible to its customers for nearly three and a half hours during the whole 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.
