EDI to DOH £470pp (T class)
DOH to KUL £470pp (T class)
T-7 days

These are for our two (adult) kids as me and my wife are already in J on redemption seats. Tempted by the DOH-KUL leg as it is Q suites and a not unreasonable price (their total return was c. £620pp).

Question: if we upgrade that leg, can they select seats for free so we grab a quad? Or will it cost £££?

TIA
