Need syntax for a ZOHO REPORTS Query | "WHERE"...

Hello:

My current Query is as follows:

SELECT
   "Passenger",
   "Travel Date",

   "Agent"
FROM "Master"
WHERE "Agent" = 'ABCTRAVEL'

Question: What is the syntax for adding ' TRAVELWORLD' to the current search criteria WHERE "Agent" = 'ABC TRAVEL' ( In laymen's terms: WHERE "Agent" = 'ABCTRAVEL' plus 'TRAVELWORLD' )

Thank you in advance for your assistance.

Michael
