Through-checked baggage - overnight
 

I will be arriving late at Heathrow T2 from FRA (LH)and will be leaving the next morning from T3 to Singapore (SQ). I will spend the night in one of the LHR hotels. Do I have to pick up the luggage in LHR only to check it in again the following day or will through-checked baggage solve this problem?

(I'm travelling on a combined ticket)

Another question. What is the probable connecting time from T2 to T3 for a First Class passenger?

Thanks in advance

You should not have to pick up your luggage, as your stopover is less than 24 hours.

If you elect to pick up your luggage, and go from T2 to T3, you will have to go through customs, etc, which takes much more time than a direct transit(never enter UK). At least an hour, probably less than 2.

Heathrow really shuts down at night. If you are planning to move luggage from LH to SQ(which I don't think you have to do), make certain the SQ booth is attended at that hour.
