below is a map of LaGuardia Airport, I will be flying in to terminal A and you will be flying in to terminal D. As you can see, the distance between them is vast.
There is a bus between the two, but that in reality is only an option for the truly desperate.
In addition, I received four pages of instructions from my car rental company and due to construction they no longer have a shuttle and may be located off-premises.
So what I propose is that I get my bag and get the rental car and pick you up White Glove VIP style at your departure terminal.
Please let me know if there is anything else you need.
