Domestic bid with LCA is way different than International 3 man bid with LCA. Domestic-Be careful accepting LCA trips over weekends (fri-mon etc.) On the first PCS run on the 20th they swap with the pot and you are left holding the bad trip w/o a LCA. International-PBS doesn't know who's senior if one of the F/O's come from another base, so look at the trips carefully. Also the F/O who gets the trip drop usually has to have the exact same footprint as the guy getting OE. Some international expert should chime in and give the specifics about who exactly gets bought off.
Goood Luck, summers here already!
