This is my first review Amazon, and unfortunately it is bad. I’m not sure that the fault lies with kayak or Amazon.
I was already well on my kayak Android phone. This version has been downloaded from the Android Market. I tried just to use Amazon Appstore recently, since some applications are cheaper here (yes, I know Kayak is free).
The version on Amazon is an older version (2.x). Said installed end, then when I use it myself, there is an update available. The update downloads OK (apparently), but are not installed. I tried several times.
I removed the software and downloaded from the Android Market and the application works fine (again).
I really expect Amazon to be better than Google in terms of “Getting It Right”, but I think that this is not the case.
