Singapore Airlines promo fares: not great, but stackable codes sweeten the deal.

A Delta customer scored a $17.34 upgrade from Premium Select to Delta One on the 15+ hour Atlanta to Seoul Incheon flight. The upgrade pricing had been $1,671 just minutes earlier — a nearly 99% drop likely caused by a pricing glitch after an itinerary change. This highlights how dynamic upgrade algorithms can produce extreme deals, so frequent checks pay off.

Delta just let unadvertised award sales drop to Australia and New Zealand from as low as 25,400 SkyMiles roundtrip, including the nonstop LAX-BNE and LAX-AKL plus connecting flights from nearly 200 U.S. cities. The sale was never promoted and rates shot up within hours on all but the nonstop segments, but hundreds of members locked in bucket-list trips for later this year. This is not an isolated glitch: Delta has dropped record-low award rates on Delta One Suites to Tokyo, Rome, Venice, Dublin, Barcelona, London, Taipei, Hong Kong, and more in the last six weeks alone, without advertising any of them. The Delta hub penalty is fading, and pricing from secondary and regional airports now often matches the nonstop rates.
