I'm flying sav-phl-bos and I found out after booking my ticket I need to get off at PHL. I know this is not allowed, I don't have the required $279 to change my flight properly so I'm just trying to figure out what to do.

This is a CRJ700. I am told that this type of plane doesn't fit hard sided carry ons and everything will have to be gate checked. Will i be able to request that I get it back at my connection or are they getting checked through to final destination?

I am considering buying a duffle bag and swapping, or just trying to carry everything in my hands that I will need for work and letting my suitcase travel to my final destination and picking it up in week.
