Which program and airline costs you least

Lisbon to Miami in business class starts at 135K miles plus $450.59 — KLM through Air France-KLM Flying Blue. Delta Air Lines through Delta SkyMiles charges the least cash — $68.22 — but wants 380K miles. British Airways Club asks fewer points, 60.3K Avios, but we do not read its cash, so it is not ranked first. British Airways adds taxes and carrier charges at booking: £499 on an off-peak London to New York Club World return since 27 May 2026. AwardWallet, May 2026.
