I have an International "B" fare and under the fare rules it has a section on transfers that reads as follows:

TRANSFERS
UNLIMITED ONLINE TRANSFERS PERMITTED IN UNITED STATES/ PUERTO RICO/VIRGIN ISLANDS ON DL. ADDITIONALLY 2 INTERLINE TRANSFERS PERMITTED, 1 IN EACH DIRECTION BETWEEN DL AND ANY OTHER CARRIER. -TRANSFERS PERMITTED OUTSIDE UNITED STATES/PUERTO RICO/ VIRGIN ISLANDS. -SURFACE SEGMENTS NOT PERMITTED. ADDITIONALLY UNLIMITED ONLINE TRANSFERS PERMITTED OUTSIDE UNITED STATES/PUERTO RICO/VIRGIN ISLANDS. ADDITIONALLY 2 TRANSFERS PERMITTED, 1 IN EACH DIRECTION IN HAWAII BETWEEN DL AND AQ.

What do these "transfers" refer to: baggage?? misconnects?. I guess I am ignorant to what this is and hoped the good people of FT could explain it better.

Edit: There is also a small section on the following:

FLT APPL
APPLIES TO ANY FLIGHT EXCEPT ANY DL FLIGHT OPERATED BY NW AND APPLIES TO ANY FLIGHT EXCEPT ANY LH/UA FLIGHT AND WHEN TRAVEL IS VIA GERMANY, APPLIES TO ANY FLIGHT EXCEPT ANY SK FLIGHT.

Does this "really mean any carrier as long as its not NW, LH, UA and SK?? So...Alitalia?? Czech??? KLM???
