I was emailed and told that if I check my luggage early I get a 10 dollar discount, also on the website, if it's under 50 lbs. it would be $40.00 I was charged $65.00 on first flight and $60.00 on second flight (second flight I checked in early, did not receive the discount, both flights my luggage was under 40 lbs.). Avelo destroyed my luggage, wheels were tore off, and plastic was ripped off.
