The number of hotel rooms booked electronically worldwide grew by 11.4% to 29.8 million during the second quarter of 2004, according to electronic marketing firm TravelClick.
Hotel revenues from e-bookings increased by 17.2% as average daily rates grew by 6.6% to $124.44 (£69.35).
While electronic room nights and daily rates rose across all hotel market sectors, luxury hotels again enjoyed the biggest growth.
Room nights in the luxury sector grew by 27.5% to 644,397 and average daily rates were up by 6.3% to $312.20 (£173.98).
London dropped off the list of the top five destinations for electronic bookings, after showing the highest rate of growth in the first quarter.
The most popular destination was New York, which boosted both room nights and average daily rates for e-bookings by more than 10%.
Travel agents continued to dominate the market, although their share of rooms dropped to 79.6% from 83% in the first quarter.
They again generated the most profitable sales for hotels, achieving average room rates that were 35.7% higher than those from other e-sources.
