A lot are talking about getting a degree in a different field as a backup if aviation doesn’t work out or the economy takes a hit.
A word of advice, plenty of people out of work for periods of time over the last year. Having a degree in a random field doesn’t automatically guarantee a job, especially if the degree was gained years before. You’ll be going up against grads with very relevant and current education and willing to work at an entry level wage.
The only ones I’ve known who were able to jump into alternate careers quick were those who had maintained their knowledge and skills in an alternate career on a part time basis whilst flying, and juggling two careers simultaneously isn’t easy.
