I have heard the following line in the TV series Narcos:Mexico :
Mañana me voy a cerrar un negocio. Ahí te aviso si todo sale al cielo.
Context: Felix, Guadalajara cartel boss, has just tried to renegotiate the terms of his cocaine transportation deal with the Cali cartel, but failed. After the meeting, he decides to travel the next day in order to get a new associate and a better deal. Then, he notifies his right-hand man (El Azul) of what he is going to do.
What does "sale al cielo" means? "to go alright" ? I couldn't find its meaning in the Word Reference dictionary.
