Flight delay this morning is causing me to miss my connection in Atlanta (delay was due to "getting numbers from ATL" I'm assuming load/balance numbers re: weight).

Currently in the air on the way to ATL so I logged in to delta.com, it shows me the list of alternate flights, however, when I select one (I've tried 10 or 12 different ones) it just loads a page saying "lets try that again." I've tried 10-12 different alternatives, all of which give me the same result.

Noticed an error code in the URL "/irop/errorSearch.action?msgCode=1103" when it returns the "try again" page. Anyone have experience with this, or know what's causing the error?
