Exactly, an awk script which prints out the commands you want to execute,
like
ln -s "./Airbus A320-200/CS-TKJ, SATA Internacional 2.jpg" "./Airlines/SATA
Internacional/Airbus A320-200, CS-TKJ 1.jpg"
...

and you test it first by doing
ls | awk ...
and see if what it prints is OK. If it is, you just add | sh -x at the end.
Here is a simple example :

$ ls -l
total 0
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:22 bar
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:22 foo
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:26 foo bar
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:22 quux
$
$ ls | awk '{ printf ("cp \"" $0 "\" \"" $0 ".orig\"\n"); }'
cp "bar" "bar.orig"
cp "foo" "foo.orig"
cp "foo bar" "foo bar.orig"
cp "quux" "quux.orig"
$
$ ls | awk '{ printf ("cp \"" $0 "\" \"" $0 ".orig\"\n"); }' | sh -x
+ cp bar bar.orig
+ cp foo foo.orig
+ cp 'foo bar' 'foo bar.orig'
+ cp quux quux.orig
$
$ ls -l
total 0
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:22 bar
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:41 bar.orig
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:22 foo
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:26 foo bar
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:41 foo bar.orig
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:41 foo.orig
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:22 quux
-rw-r--r-- 1 slt Aucun 0 Apr  4 14:41 quux.orig

Don't forget the quotes around file names ! ! Files can contain spaces
and/or other nasty characters !!
