at a time. You're slowly tweaking the
system to make sure that you're not
causing new issues or things that you
may not have thought about. "
" When changes are made to the
system, it is critical to implement
them when the operation can be
evaluated over time, " Farley said.
" Adding humidification during the
summer months allows the work
to be performed and the sequence
of operation to be verif ied prior
to the drier winter months when
humidification is needed. "

Meyer said LNAA is considering
two potential options: installing UV
lights or other components into their
existing HVAC systems and equipping
the new security checkpoint with
proprietary equipment with the
ability to remove pathogens from
the air.
" Unless you are doing a major
upgrade or renovation, there's very

little you can do about the existing
air circulation within the facility
other than simply replacing air
f ilters. You can keep the system
fans running longer than they had
before with potential for greater
outside air inclusion if the system
can support it. But in general, unless
you make a substantial investment,

it's pretty challenging to make
signif icant upgrades, " Meyer said
of making changes to their existing
infrastructure.

Meyer said the LNAA is keeping the
future and their passengers in mind.
Meyer said he sees a post-pandemic
future with passengers remaining
health conscious and aware of what
illnesses they may encounter while
travelling, so any project needs to do
more than in the past to ensure people
feel safe and confident to f ly through
our facility.
" If you look back in history, it
seems there has always been some
type of respiratory virus, contained
to specif ic geographical areas.
COVID-19 has obviously had a
global impact, but it just makes you
wonder what other variant do we not
know of that could be coming in the
future? " Meyer said. " And that's one
of the main elements we've talked

our checkpoint, is trying to plan for
the unknown and provide a safe and
healthy facility for our passengers.
" We're all learning and adapting
to this COVID-19 pandemic. But if
something like this happens again, or
some version of it, we want to make
sure that we have done everything we
can to be prepared for it, to keep our
passengers and traveling public safe
as they come to the facility, even as
it relates to the seasonal f lu and other
pathogens. " he continued. 
