Budget Travel - How to know STA.UK blue tix booking class?

Different from STA.COM, UK website does not provide the booking sub-class when booking online. You only have a chance to know it till you get the confirmation.

When I go to the branch or call their service enter, the staff were not happy to check it for you.

Any expert can help me to check STA.UK booking class? I really need to know it for FFP miles earning. Iam looking for one-way tix from LHR to JFK on August 31 and focus on BA or AA for CX miles earning.

Please inform me these all-in prices' booking subclass (shown on their website)

LHR/JFK AA 262 269
BA 274

Many thanks.

Odd that they wouldn't tell you...in the US, Ive called the toll free number to get fare classes. Try that?
