I assume your flight is too early tomorrow for you to get to the DMV to get a new id before leaving (assuming this is the origin of your trip)?

You will be allowed to check in... as long as it is domestic... and you will go through several searches.

Also, make sure you have cash for your trip in case some places do not take your credit card... especially if your card requests they check for ID.

Make sure you get to the airport extremely early to allow for the extra time it will take... it will take time... and you really are at their mercy.

GOOD luck....
