Baggage to Final Destination with long layover
We fly the following:
APR 5 2005 2235 DPS-SIN SQ947
APR 6 0045 0710 SIN-LHR SQ306
APR 7 0650 0905 LHR-BRU SN2104
APR 7 1200 1420 BRU-IAD UA951
Will the SQ check in at DPS be able to check our bags all the way through to IAD, or will we have to claim and recheck at LHR. This would be desirable as we can go into London for the day and overnight stay with only carry-on.
