Friends, Romans and Countrymen(and women) lend me your ears....

My daughter is a flight attendant for Delta, I'm working on my daughters taxes and on her W-2, in box 14 the following acronyms are listed with amounts next to each:

OTH FRINGE

TAFB

WA PFML

I understand that the first is other fringe benefits but unsure of the other two?  Also are all of these items considered taxable income?

Any assistance would be greatly appreciated

Thanks!
