Hot take: I think packing only a carry-on is overrated for saving money
Lots of folks swear by packing light to avoid checked bag fees, but I've found that isn't always the smartest move. For longer trips, I need to buy essentials at my destination, which ends up costing more than a checked bag fee. Last year, I paid $30 for a checked bag but would have spent over $50 on sunscreen and extra clothes I forgot. Having my stuff with me means I don't waste vacation time shopping for things I already own. Plus, some budget airlines charge just as much for overweight carry-ons. Being able to pack properly has saved me stress and cash in the end.
