Are you planning on changing your last name to your husband's after the wedding? There are number of companies and government agencies you'll need to reach out to - social security, department of motor vehicles, credit cards.
But since you won't be filing the paper work until after your wedding and probably after you returned from your honeymoon make sure you book your flight and hotel reservations in the name that appears on your current ID cards - passport, driver's license - and that would be your maiden name.
You can still let the airline and hotel that the reason for your trip is your honeymoon and enjoy any perks like free champagne on your arrival.
