I am due to fly on SAA and have not flown with them before. Hopefully there are some people here who can answer some of these questions:

1. I am flying LHR-JNB-PLZ in economy...is there always one vegetarian option for the meals or do I have to order one in advance?

2. I am Star Alliance Silver...can I use the business class check-in desks at LHR and JNB domestic?

3. I want to shower in between flights and grab something to eat. I am a Priority Pass holder so could use the Bidair Arrivals Lounge or the Bidair Domestic Departure lounge...does the departure lounge have adequate showers or would I be best using the Arrivals lounge? What about the food?

4. I am scheduled to fly on the earlier flight to JNB but if this flight is overbooked, could I volunteer to fly on the later flight in exchange for cash and/or an upgrade? Would SAA rebook my connecting flight to PLZ if I opted to do this?

Thanks!!
