Hi House,
I was able to purchase a two-way ticket for my wife and myself to New York @ the cost of 1,331USD each from Delta Airlines. As adviced by Gh-Man, i went to
United Airlines office to enquire about the cost of ticket to New York and it was 1,560USD. It was a transit via WDC. I also realised that these two airlines fly direct to different states in the US so depending on where one is going, it's better to check out the one that offers a lower fare.
Good, you are now on course! Welcome to America.
Hope you have a better preparation and safe journey to the US.
When the time draws near for you to depart,
let us know so we can invoke the holy spirit to protect you on your way.
