Where is the pilot flying to? (Fourth destination)

This is the fourth in a series of puzzles where the answer will always be an international airport. Previous puzzles can be found first, second, and third. The puzzles are all independent, but follow the same general format and story.

Barry was enjoying his time relaxing after the last job, but work must go on, and he just received a rather long letter from the Don.

Barry,

There are only two kinds of people in this world, those who act
against me and those who support me. The first are nobodies. They are
worth nothing, not my time, and certainly not worth my money. The
second group are all that matters. Those who, like yourself, have
proven themselves worthy of my interest.

Mr. Smith, and his daughter Ms. Doe, have recently found themselves in
my displeasure. I find myself unsure, a rare occurance for me, on how
to proceed. If I am still concerning myself with them, are they truly
nothing… After all, they did not go to the FBI like Moore, Thompson,
and Bawling. Now that was disappointing. Still, I cannot say it was
entirely unexpected. There are those in this world who simply do not
have the constitution to do this line of work, not like the old days.

Forgive an old man his nostalgia, unseemly though it may be, as these
days it is the only solace still available to me. Things have changed
so quickly. This world, sometimes I think it no longer welcomes men
such as myself. However, as I think on it some more, I think that it
is men like myself, like you, who truly make the world work. We are
not afraid to get dirty. To do what must be done. To risk it all,
everything we have built, to see that things do not become stagnant.

Now on to subjects which, although more pleasant, are no less
important. Your next task should be rather enjoyable. I believe this
is not only the first time you have visited this country, but also the
first time you have been in this time zone. You will probably suffer
some jetlag, in fact I am fairly certain you will, so you should
prepare to rest for a couple days, perhaps even a week, before
returning home. I would encourage you to make the most of this time,
think of it as a well deserved vacation. Of course that is to happen
only after you complete the task at hand.

When you return, I will need you to talk to Alan, Bob, Charity, and
Daniella. We will need them to help us get several items, including
1,000,000 Vietnamese Dong, 2,000 pounds of butter, and 50,000 dollars. We
should be able to get a solid return on this investment. I would be
surprised if we do not net at least 1,000,000,000 dollars by the end of the
decade. I believe you will be able to afford a second plane, perhaps
even a Gulfstream, when all is said and done. You will need to take me
on a ride when you do so.

The current operational budget is $316,402,977.53. This is definitely
a good thing, in fact, I believe it is the highest we have ever
enjoyed. We must make sure we stay profitable. I do not want to go
back to where we were two decades ago. Ahh, look at me being nostalgic
again, oh well. Alas, this has already been a very long letter, but I
beg you allow an old man time to ramble. People really just don’t
write enough letters anymore, only email…

Anyway, I am sure you already know this, of course, but do not forget
to bring your mask. Things the way the are now that is cruical. It is
imperative we do nothing to stand out, nor to invite even the most
cursory investigation of the authorities. Your paperwork should all be
in order. Do not worry about being denied entry. I can assure you, I
have personally seen to all of the necessary details, and I will take
responsibility for any mishaps.

I will provide some more details. Take the first train available,
after you land and go through immigration of course. Get off at the
third stop. Go to the store across the street. There should be a man,
five and a half feet tall, behind the counter. You will ask him for
directions to the festival. He will say he does not speak English. You
are to ask again, and this time he will bring out another worker, a
man who will call himself Abe. Walk outside, following Abe, and he
will point out another man he will identify as Mr. Tony. This will be
your primary contact.

Sincerely, with wishes of luck, your friend,

Don

Can you use the Don’s letter to figure out where he has Barry flying to next?
