Business the play 99,000 pts British Airways nonstop (relaunched Apr-2026), Club World off-peak
99,000 off-peak / 110,000 peak one-way on BA's per-route list, and the ex-CMB direction dodges the £244 UK APD entirely (£249.50 is the ex-LHR copay). SriLankan's nonstop books off the 4,001–5,500 partner band and should price under this — we haven't found the post-devaluation band published, so BA is the row we can prove. Qsuite via DOH sums two legs past the nonstop.

Etihad via AUH (one stop) — GuestSeat, calculator-priced
Etihad flies CMB–AUH daily and connects to London, but GuestSeat pricing comes off a calculator, not a chart — the documented India-to-London datapoint ran 100,005 miles plus ~₹44,000 in carrier charges. Expect Colombo to price in that unhappy neighbourhood. Listed so nobody discovers it the expensive way.

Emirates via DXB (one stop) — Classic Rewards, calculator-priced
A calculator price, a May-2026 devaluation (+15% premium cabins), a Dubai connection and Emirates' heavy carrier surcharges — every part of this stacks against the published nonstops. Only for Skywards balances with nowhere else to go.

Economy the play 33,000 pts British Airways nonstop (relaunched Apr-2026), off-peak
BA's post-Dec-2025 route list: 33,000 off-peak / 38,500 peak each way, either direction. The £85 copay HfP quotes is the ex-UK figure; ex-CMB the cash side is unpublished but structurally lighter — no UK APD on a Colombo departure.
