Answer 1

With UNION , you have to make sure both queries have same number of columns.

Second query doesn't really need to include names because it will use the first query names, but you include it for clear reading.

 SELECT travelname, 
        bemail as email, 
        mname as name
 FROM mytable

 UNION

 SELECT travelname, 
        temail as email, 
        tman_name as name
 FROM mytable
