I am a companion on my sister's pass, and she is a former employee (not retired), so we are S3.I need to check 2 boxes as baggage, from St. George, UT to Maui. both boxes are 48 pounds, and 60 inches total dimensions (18+18+24). My understanding his that for both, the 1st and 2nd checked pieces, the fee is waived. Is that True or False? Will the boxes even be accepted at check-in? Will there be fees? Thanks for your help.
