This is my first time flying a while and I don't rember the requirements for the baggage like the measurements and weights. Also, was curious if you can have a carry on with and additional purse or bag or backpack.

Check with your airline

It depends on the airline, check their website.

Please visit your airline website. In general a small carry on and a purse or backpack are permitted.

It's all on their website . But as far as carry on, you can not bring anything else besides ur purse unless u pay $25 for it. Also no tv on board.
