Know you Luggage Limitations. Certainly luggage allowances have changed over the years. Check with your carrier/travel consultant before your next overseas trip. On many smaller, overseas carriers, luggage is a highly restricted – and profitable – line of business! So, if you have other flights, check their limitations and know that any exception will be expensive. And if you’re planning on carrying MORE home than you came with, make sure you have “planned” the room for your acquisitions.
