Ok, so after reading through the script I found here, at one point a plan to just abandon the ship was suggested and promptly thrown out.

Ripley: Unless someone's got a better idea about dealing with the Alien, we'll proceed with Dallas' plan.

 

Lambert: And wind up the same way. No thanks.

 

Parker: You've got a better idea.

 

Lambert: Yes. Abandon ship. Take the shuttle craft and get the hell out of here. Take our chances on getting picked up later.

 

Ash: You are forgetting something. Dallas and Brett may not be dead. It's a ghastly probability perhaps, but not a certainty.

 

Ripley: Ash is right. We've got to give it another try. We know it's using the air shafts. Let's take it level by level. This time we'll laser seal every bulkhead and vent behind us until we corner it.

It isn't until later in the movie once Ash is revealed to be an android and that his mission is to bring the alien back alive, while the crew of the Nostromo are all expendable that it's decided to self destruct the ship, ensuring the Alien is dead and Weyland-Yutani never gets their hands on it.
