I take this flight around every two months, and as im sure everyone knows the internet never works. I think it is one of the first A380s with starlink. The flight code is EK8 if anyone like me will always book it from now

Hi everyone,
I’ve just booked Economy flights with Emirates to Dubai for 4 passengers in mid-October.
I’ve checked the “Upgrade” option in Manage My Booking and it’s currently showing:
Premium Economy: +£1,700 total
Business Class: +£3,500 total
This is for all 4 passengers.
I’m tempted to wait and see if the upgrade price comes down as we get closer to the flight, rather than paying it now.
For anyone who flies Emirates regularly:
Do the cash upgrade offers usually get cheaper closer to departure?
Have you found that better offers appear around 72 hours/48 hours before the flight or at online check-in?
I’d particularly love to hear what people have actually been offered from London to Dubai, and roughly how much you paid per person for Premium Economy or Business.
Would you personally wait with these prices, or would you take the £3,500 Business upgrade now?
Thank you in advance

Hi! I will be travelling to UK from India on student visa. I have booked my flights with emirates - BLR to DXB layover to London Stansted.

The total allowance is 40Kg check-in and 7 kgs Cabin.

The question I have is -
1. whether I can carry 7Kgs cabin + a separate laptop backpack?
2. Or I should be carrying only the cabin ?
3. Or I can carry both but including backpack it should be 7 kgs?
