Flying out of LGW on a 9:45AM LH flight on a Thursday morning to FRA. Leaving from post code W1C (Marble Arch/Bond Street tube station area – haven’t finalised hotel yet).

Flying business class, so should be eligible for priority check-in and security screening. Latest check-in time accordance to LH web site is T-40 min.

There will be 2 adults, with 2 suitcases & 2 carry-on.

Should I take the Gatwick Express from Victoria to avoid the usual morning rush hour, or will a car service pick up at around 6:45~7AM be okay?

Thanks!
