Watch how many bags you take on the plane,
has airline rules ( most cases ) state one piece
of hand-luggage per person.
If you decide to shop in the airport, say a couple
bottles of spirits, cigarettes, cigars & perfume,
even bottles of water.
Like me, got my flight bag, my wife has her hand
bag, then we both have a bag each of airport
Turns out airlines are getting strict, & charging you
for the extra bag (s).
The airlines are doing this, to deter passengers
from buying in the airport, & in stead making the
passengers buy on the aircraft.
I always make sure that I can get my airport
shopping in my flight bag, they are not getting owt
out of me.
Before buying at the airport, check on-line your
aircrafts flight magazine, to check prices, then you
know which is the cheapest.
But beware even though the flight magazine shows
a item in it, it does not mean they have it.
I have found Thomson's aircraft cheaper than airports
in the past.
Happy shopping !
