I have never been so frustrated by a website. I somehow managed to book one flight today, but now I can't do anything without being told my session has expired. The reassurance that I will be able to go back and finish what I started is like salt in a wound - I have restarted at the beginning so many times that I am surprised my iPad is not lying across the room in pieces. The login box is tiny and half hidden at the bottom of the page so that a click often fails to bring up the keyboard. Flight search pages take forever to load, and while they look complete, scrolling is impossible - popping back to the top as soon as it is released until the wheel stops turning, often over a minute per page. I have restarted everything many times, checked all the requirements for browsers and OS, all should be fine, but it is a complete mess. I have submitted several complaints - not even one acknowledgment that they have been received. I thought the new iPad app might address some of these issues, but it just sends me back to the impossible web site. Honestly, I am at a loss for words and ideas - other than to boycott Delta until they fix this.
