I will be flying on SQ from SIN into LAX and then from LAX to BWI on UA. Singapore Airlines allows me 2 pieces of 32kg.
When i land at LAX (International), will I need to retrieve my baggage and re-check in or will my baggage be checked all the way to BWI from country of origin?
The big question is also, will UA allow my 2 pieces of 32kg since I came from an international flight (that has a different baggage limit)?

Thanks
