I'm sure you'd be able to do sufficient damage to the airliner, without having to kill yourself. If you do significant damage to your own aircraft, then you can just eject. I'd certainly try to damage the target with my own aircraft, but I wouldn't go flying in at it nose first.
You know what I'm going to try on Lock On, now...

But obviously you would be willing to lay down your life if you had to?
Without being patronising, to your age of 16 you have not seen that much in this world. Living a life so far of Hollywood and computer games, once you have seen a few dead bodies, been sent to hot sandy places or even a few places not to far from your present location, you will learn that anyone who has experienced such things has a great urge to cling to life for as long as possible.
Would you be willing to lay down your life? That is a sentence devised to lessen the blow of informing a relative that you are DEAD, no more, splashed to the 4 winds, end EX. "Where's daddy", "gone to a better place my child". What is better than coming home to your child?
If I had to lay down my life,
If I had to, there is always choice. There is no obviously about it.
