Probably not.

Even if you're doing online banking on airport wifi, the more likely ways you're going to get hacked are:

1. the dude watching over your shoulder as you type your password
2. someone hacking your bank or a merchant with whom you've done business
3. someone hacking another website that stored passwords in cleartext and using the password elsewhere (but you'd never use the same password on that dodgy forum for owners of 1984 Pontiac Fieros as you use for your bank... right?)

TLS (the encryption behind https, etc.) is quite secure and essentially every legitimate organization uses it these days. The alleged dangers of public wifi are, IMO, grossly overstated in 2019.
