11 Practical Hacks to Avoid Excess Baggage Charges and Save on Airline Fees

5. Maximize your carry-on plus personal item

Many travelers can avoid checked-bag fees entirely by making the most of carry-on and personal-item allowances. First, confirm size limits for both items—size enforcement varies by carrier and sometimes by gate agent. Pack a well-organized personal item that fits under the seat and contains heavier essentials to keep your carry-on under weight limits. Use slim packing cubes to create space and keep your personal item accessible; items you’ll need en route, like a charger or a light jacket, should go in the personal item so they don’t take prime space in the carry-on. If you need toiletries or a small laptop, place them in the personal item to avoid moving them between bags at the gate. Practicing a carry-on-only setup before a trip helps you learn what fits comfortably, and a measured test run with a luggage scale and a tape measure at home prevents surprises at security. This approach is especially useful for short trips where laundry or quick wardrobe combos can replace bulkier packing.
