Business Class - MEL -> SIN

Provided both sectors are in 1 booming then YES you can enjoy ALL benefits applicable to the highest cabin level in the booking.
Yes both flights are shown on the one booking reference number. The Singapore airlines phone assistant told me to go to Business class check in desk and have fun at business class lounge. It didn’t sound right since the final flight is first class, I’d imagine it would get first class baggage tags and sent directly from Melbourne to Dubai?
 
IIRC there will be no F check in counter for SQ248 as no F on the service. You might need to remind the check in for F tags though. Fairly certain you will be able to get in the F lounge.

ChatGPT seems to think otherwise (the same as the phone staff at SIA).

Apologies for any confusion in my earlier responses.





You’re correct: Singapore Airlines’ Airbus A350-900, which operates the Melbourne to Singapore route, features Business Class as its highest cabin class, without a First Class cabin.

‘Given that your Melbourne to Singapore flight (SQ248) is in Business Class and the Singapore to Dubai flight (SQ494) is in First Class, and both flights are under the same booking reference, your lounge access in Melbourne is determined by the class of service for the departing flight from that location.

Lounge Access in Melbourne:
  • Class of Service: Your departing flight from Melbourne is in Business Class.
  • Lounge Access: As a Business Class passenger, you have access to the SilverKris Business Class Lounge at Melbourne Airport. The SilverKris First Class Lounge is reserved for passengers departing on a First Class flight from Melbourne.

Lounge Access in Singapore (Transit):
  • Class of Service: Your onward flight from Singapore to Dubai is in First Class.
  • Lounge Access: In Singapore, you are entitled to access The Private Room, Singapore Airlines’ exclusive lounge for First Class passengers.
In summary, while your First Class segment grants you access to The Private Room in Singapore, your Business Class departure from Melbourne provides access to the SilverKris Business Class Lounge there.’

Is that the response from SQ, or the google search generated response?

If that’s from SQ, there are a couple of things which might explain it.

Firstly, whomever wrote it isn’t really familiar with the intricacies of lounge access, and has given you the standard answer for star alliance access rules.

Or (b), the ‘lounge access based on highest class’ applies to mixed cabin bookings only, where the highest class has been paid for the entire ticket, but you travel in a lower class for one or more sectors.

In (b), and uograde on one sector may not qualify. Unless you upgraded the entire ticket to F, and chose to travel in J for MEL-SIN.

What does your new ticket show for the underlying fare basis for the whole ticket?
 
Thanks for your reply. This is what the ticket shows:
It could be up to the underlying fare basis of the ticket. Not your itinerary as you have attached.

Your itinerary will be the class of travel, but that doesn’t indicate the fare basis.

You can have first class fares issued where part travel is in a lower class. That’s usually because F is t offered on a route. For example you can buy a first class fare from SYD-BKK where the SIN-BKK will be in business.

Your case might be different - don’t know. Did you upfpgrade one sector, or did you upgrade the whole ticket.

The distinction may be important in the reply given to you.

However, that aside, will the lounge staff be interested in that? Possibly not. Showing both boarding passes may get you welcomed into the F lounge.

Yes, when booking I could only book business class due to the A350-900 only having business class cabin. I then realised the next flight was a 777-300ER and paid the upgrade to first on the same booking reference and had the ticket reissued.

Yes, and the key question is - potentially - how that is reflected in the fare basis. The answers you are getting from SQ may be taking that into account. But in practical terms it may not make much difference.

I’ve checked the eticket:

ChatGPT says:


Here’s what your fare basis reveals:
  • First flight (MEL–SIN): Business Class (D) – This is a discounted business fare.
  • Second flight (SIN–DXB): Suites/First Class (A) – This is a full First Class fare.

So what does this mean for your lounge access and check-in in Melbourne?

Technically:
  • Since your first flight is a D-class Business fare, and that’s the departing segment from Melbourne, you’re only entitled to Business Class check-in and lounge access there—on paper.
However:
  • Because your overall itinerary includes a full First Class segment (A fare), and both flights are under one booking, you may be granted First Class lounge access and check-in as a courtesy, especially if you show both boarding passes.

What to do:
  • At check-in in Melbourne, mention that your onward flight is in Suites/First, and that it’s under the same booking. Politely ask whether you’re eligible for First Class check-in and lounge access.
  • Show both boarding passes at the lounge—often staff will allow access based on the premium segment in your itinerary.
In short:
You’re not guaranteed First Class lounge access in Melbourne due to the D-class fare, but it’s very possible you’ll be let in, especially if you ask kindly and present both segments.
