Avoid Hidden Costs When you Fly
What are the hidden costs of flying?
There is no "standard" size for carry-on baggage – each airlne sets its own policy, so we have put web links and size information for most of the popular worldwide airlines in one handy chart.
Don't end up at the airport with a bag that must be checked for $15 – plus a bag you thought you could carry on, that must now be sent back outside the security lines to be checked – with the result that you end up with two checked bags costing $40 ($15 first, $25 second). Measurement is in maximum "Linear Inches" which is Length + Width + Height (total inches).
Airline reservation systems require everyone on the same booking to fly at the same price. If you book tickets one-at a time, and you may find cheaper individual fares. Just double-check seat assignments if you must sit with your other passengers.
