Okay|Mar 2022

We paid $47 to check one carefully packed 50 lb bag on the way. Our return trip, they charged $65 for the base fee and only then chose to inform us that we would be required to pay an extra ONE HUNDRED DOLLARS - total of $165 one way! A because, since our departure, they had reduced the permissible weight to 40 lbs. ONE HUNDRED ADDITIONAL DOLLARS FOR LESS THAN TEN POUNDS WHEN WE WERE TOLD 50 LBS WAS THE LIMIT. I know their fares are cheap but my lord, their seats are tiny, they nickel and dime EVERYTHING, and they legit steal from you by changing the rules and price-gouging. Gross. I’ll pay more on the front end next time, because at those prices I could’ve flown a non-budget airline and been comfortable and had a damn complimentary water.
