You are allowed 2 bags 50lbs each, how many more you will be carrying? you can use boxes too, just check the dimensions, if you will be adding few more bags than take them with you by air, emirates charge less if paid on line before your flight, some charge $200 for additional bag 50lbs, some airline charge only $50 more if free bag (first 2)weight is more than 50lbs but less than 70lbs per bag.
Check with local travel agent or airline for their weight and additional bag charges, but keep in mind that not all airlines fly to Pittsburgh, if you have a domestic connection here in US, if that airline will charge you extra for additional bags. On domestic they will allow one bag free,second bag is $70 on united,this info should only be used for flights from south east Asia to US on direct flight one ticket. if this option is expensive than you can book by sea.
