I have found a flight in Hawaiian airlines which is having connection 1 and the ticket fare is 300. Is it ok  for you?
Please do not book flight.
Why, may I know the reason for not proceeding for booking?
Fare is 300. Thanks.
Oh! Let me check once again for flight under your budget, ok.

Let me know your good name please to call you in better way.

Sorry, no airline is running a flight in your route under your budget limit because it is a longest route.
