Before purchasing a new piece of carry-on luggage,
make sure it meets the most restrictive dimensions – 22
x 14 x 9".
Most airlines limit the number of carry-ons to 1 piece,
but often exclude business cases, computer cases, handbags,
diaper bags, coats and items to assist those with disabilities.
Alert: When packing, do not overstuff a legitimate
carryon; this may effectively disqualify it.
