Greetings Everyone,

I have a flight as;
JFK-DXB 23:00pm-20:15pm (Duration is 12 Hr, 5 min)

Connection is 7 hr, 10 min

DXB-ISB 03:25am-07:30am (Duration is 3Hr, 5Min)

I have upgraded the first leg from economy to business class. I also wanted to upgrade the second leg but it does not show any option for upgrading the second leg to business class.

Is it possible to get a business class on the second leg by anyway?
I also would like to know if there are any good seeping places sincemy entire connection will be during night .

Thank you for any insight.
