If your need to book a flight, hotel or car using your phone the latest version of Online travel giant Travelocity's mobile site is probably not your best bet.
The mobile homepage is nicely formatted and looks good in Android and Symbian browsers, but clicking any of the booking options leads to Travelocity's desktop site which really doesn't work very well on any mobile device. I suspect that calling Travelocity using the provided click to call number would be the best way to book while out and about.
There are some potentially useful mobile friendly features on the site, a flight status checker an another one for checking airport security wait times. Too bad they don't work. I don't trust the flight status after it showed a flight leaving Dublin 7 hours late and arriving in Newark only 50 minutes late. Pretty sure that's impossible.
Then there's the security wait time checker. Sounds handy except that it returned "There is no Security wait time data available for your query" for every airport I checked including JFK, SFO and LAX!
While I like Travelocity's desktop site, it will be a long time before try using the mobile one again.
