I second the above. An employer I know of offering excellent terms and conditions and known to be a "good" company once asked a candidate at interview about his current notice period. The candidate enthusiastically answered it didn't matter and he could start whenever this prospective employer wanted. He did not get the job. Their view was if he'd do it to his old employer he'd to it to his new one and they couldn't trust this person.
Love them or hate them, Ryanair is not the company you want blacklisting your name. Covid taught us all one thing, you never ever know what is around the corner. You say all this now that you'd never go back, but after say 3 yrs of unemployment and bills banging on the door, you may view things very differently at some point. Best of luck
