A spokeswoman for Delta says the airline will try to resume the flight on a seasonal basis, but can't say when.
The spokeswoman says the Bradley decision and all other Delta route changes are absolutely tied to the spike in fuel prices.
Delta, Bradley's biggest carrier by passenger volume, said earlier this month that it would cut service between Boston and Los Angeles in August.
Delta operates Hartford-Los Angeles flights four times a week and has been serving the route for about three years.
