Hello everyone! I’m Shinchannohara. I just checked out the Sun Country Airlines Baggage Policy Country Airlines to help make your travel easier. You can bring one free carry-on bag that weighs up to 7 kg (15.9 lbs) and should not be bigger than 43 x 33 x 22.9 cm (17 x 13 x 9 in). If you need to check a bag, the first one costs between $30 and $45. It can weigh up to 23 kg (50 lbs) and should not be larger than 158 cm (62 in) in total size. If you want to bring extra bags or oversized items, there will be additional fees. By knowing these rules, you can avoid surprise charges and have a smooth trip with Sun Country Airlines!
