how much is the charge for luggage

It depends on the airline.

A good rule of thumb is that low cost airlines will charge for every bag that's checked.

The luggage cart is $5!!!

I bought a really nice bag for about fourty5 dollars!

Depends on the airline, Southwest Airlines allows two checked bags for free, but most charge $25 per bag, which must not weigh more than 50 lbs

I think that Southwest Airlines doesn't charge for the first two luggages and allows one small carry-on. It is best to check with the airline itself for the most accurate information.

Depends on which airline you choose.

1 normal sized luggage is $25

If you have more than allowable limit you may need to pay from 50 to 150 dollars
