Looking at booking a MFU in Club World LHR-LAS returning MIA-LHR. Would it be possible to include a stopover at SFO so the booking would be LHR-SFO-LAS then return MIA-LHR?
The reason I ask is that I would be flying SFO-LAS on United with suitcase weighting between 23kg-32kg. There are no fees on BA travelling Club World but the United flight ( and others on the route SFO-LAS) are charging at least $75 for each case over 23kg.
By adding this flight to the MFU booking, I assume I would not pay any baggage fees to United because the MFU booking contains the main flights in Club World so no charge for any baggage.
Any info would be useful regarding planning a trip from LHR-SFO-LAS and returning MIA-LHR as a MFU.
