Dear EK experts - I am on EK 622 in J class and the availability for the 15th Jan. 07 is the following today:

EK 622 DXB 03:40 LHE 07:25 772 J0 C0 Y0 W0 M0 B0 K0 Q0 H0 L0 T0 V0

Since I have nothing to do in Lahore on Monday I do not mind to stay a day in Dubai - what are the chances to get DBC or downgrade compensation. Second question: is this 777-200 with new business class? Thanks
