Trying to figure out the best AWARD routing to Croatia. Preferably to Zagreb, but other cities OK too - or in to Zagerb and out from Dubrovnik. Also would prefer First in a 777 overseas.

I know we can fly DFW - MAD. Did I read somewhere that the use of a 777 on this route is seasonal?

The best connection is to IB since they have a direct flight, but it appears to be seasonal, which limits our travels to July - mid Sept. If we wanted to travel in May - do we have any other options besides Malev - which would require flights to Budapest and possibly a very long layover?

Would I be better getting a flight to/from LA-LHR and then paying for an Easyjet ticket on my own?

Is there a oneworld Carrier that has better options?
