Chicago officials say there'll be extended bus and train service operating this weekend because of the city's annual Air &Water show.
The show is Saturday and Sunday. In a news release, the Chicago Transit Authority officials say they will be longer trains operating both days on the blue, brown, orange and green lines. Officials say those riding the brown line should allow extra travel time because of a weekend track closure.

There'll also be additional bus service on two routes.
The agency also encourages spectators to buy ride passes ahead of time to avoid long lines.
