regex notepad++ select a word immediately following ( & preceding ) selection

Question

I need to select just the word that follows a specific selection ( and one that precedes it - both are separate regexes - not to be combine em )

the pattern is 
<variable verbiage>
 <one or more spaces or a newline>
"on"
<one or more spaces or a  newline>
 Word_to_select
<optional variable verbiage>
Examples 
1 ) she looks too pretty I never meant Hillary ya da ya ON delta.airlines next word 
2 )yada ya        
Daddy Daddy
     on
united.airlines  hullah
gulla ; 
 3)yada ya         Daddy Daddy  on
American.airlines some 
ricotta cheese 

I need to get in all cases
'Following' regex :

delta.airlines
united.airlines 
american.airlines 

'Preceding' regex :

ya
Daddy
Daddy

What I tried

(\S)\s* on \s*(\S+)

the selection includes "on" and goes back further .

Answer 1

Look this demo. you can select group 1 to get "preceding" and 2 to select "following".http://regexr.com/3g7ps

Answer 2

You may use

\bon\s+\K\S+

See the regex demo.

Match case option should be deselected or just prepend the pattern with (?i).

Details:

• \bon - a whole word on
• \s+ - 1 or more whitespaces
• \K - match reset operator
• \S+ - 1+ non-whitespace symbols.
