Hi Sharon and anyone else out there going on the September trip to New Orleans etc. it may help you to know that when applying on line for your visa waiver the following information is required.
Therefore under the question address line 1 you should enter:- 1201.
address line 2 :-Convention Centre.
City:-New Orleans.
State:- Louisiana.
The flight no to be entered is Delta airlines DL811.
I hope this helps.
