"Have a safe trip"… or not, depending on four conditions
When it comes to long and complex logic summation I recommend, as Legato says, to use one row for each condition. 
I also think it is more readable if you sum all the conditions to a new variable that explains the result with a meaningful name like this:

boolean isTripPossible = 
   !isNameBlank &amp;&amp; 
   !isDestinationBlank &amp;&amp; 
   isDestinationValid &amp;&amp; 
   isAmountValid;      

String message = isTripPossible ? "Have a safe trip!" : "Please try again!";
