BA Domestic then SQ Longhaul

[BA Allowance]

Have looked at both BA and SQ websites to find out as I have solitaire status with SQ i have 40kg checked in allowance when i travel economy.  I am due to travel to the UK on SQ using my 40kg allowance in economy then i need to i then need to take a BA domestic flight.

Does anyone know if BA will allow me the extra luggage allowance without charge seen as I have it with SQ and I am on a connecting flight to my final destination

Any help appreciated

many thanks

It's doubtful.

Have you booked the entire itinerary in one go with the same confirmation number for both legs of your flights, or do you have two confirmation numbers for each flight (ie. seperate bookings?).

The problem is that SQ is a member of Star Alliance (where you have status) but BA is a member of the One World Alliance - where you presumably don't have status (unless you have with another airline in the Alliance eg. Qantas). If BA was a Star Alliance member there would be no problem with the extra luggage allowance, interlining, use of airline lounges etc. but it doesn't apply in your case.

I recently flew from Zurich to LHR on BA and then Virgin Atlantic to New York and BA wouldn't interline my bags, so I collected them at Terminal 5 and took the Heathrow Express train to Terminal 3 and re-checked them at the Virgin desk. These flights were booked seperately, however.

My guess is that you will have to pay for your extra baggage for the BA sector. Call them and they'll let you know one way or the other.

I've never flown domestically within the UK (although I'm a Brit) so I don't even know if your baggage will be interlined (again you are flying with different airlines/allowances/terminals etc.).

In the US all baggage has to be collected off the carousel at the Port of Entry, one has to go through Customs and then baggage is re-screened for onward domestic flights. I have no idea if they do this in the UK, but it's more likely that it is done at the final destination (not that one often sees Customs Officers at even LHR these days). I guess someone else here will come along soon who has taken incoming overseas flights and taken the onward connection with a different airline via LHR to Glasgow, Manchester etc. and will let you know about this....otherwise ask the airlines. 

[done it before in US]

I recently flew to New York on SQ then had a connecting flight (non-star alliance) to Boston which I booked on a separate ticket.  I asked SQ to check my bags all the way through to Boston.  The SQ lady at the counter was a bit hesitant to do this as I had to collect my bags at JFK for customs & immigration.  I told them I understood that but insisted they do it anyways.  (Be sure you give them the correct airport code for your final city). This way SQ is held responsible for your bags in case there are delays and you miss your connection.  Once I got to JFK, I collected my bags, went through immigration, then dropped them off at the SQ transit counter.  There were no problems at all and I was not charged extra baggage fees (which can be quite high in the US) by the domestic airline.
You might also want to search the "flyertalk forum" (google) for this.  I've gotten very good answers from some expert frequent flyers on that site.  let us know the outcome.

[My thoughts are]

the same as the poster above. You will be OK if its one ticket and the BA domestic is part of the SQ ticket through. If its a separate domestic ticket booked on BA they may charge you for the extra 20k depending how charming you are and how bad the battleaxe is checking you in for the domestic flight.

As I said though if you are checking in at Changi all the way to final destination it will be fine.

[Problem]

Unfortunately, the problem will probably be that you are only allowed 1 bag up to 23kg on domestic BA.  2 bags at less weights is not allowed.  They really stick to the 1 bag rule.

Another problem will be, if you are going through Heathrow, they are B@#$#rds and will stop you if your carry on is too large and make you check it in - at your cost, of course.  I don't mean something huge but if it doesn't fit into their size rack you are stuffed. Oh and don't expect them to be polite about it!  I think Heathrow is now one of the worst airports in the world - and I'm a Brit. As PPs have said, try and get SQ to book all the way (or take a train).
