Delta

Delta is offering up to a 50% bonus on purchased SkyMiles through September 30, 2026 – full tier breakdown, and when buying miles actually makes sense.

Delta ticket numbers start with 006 – a 13-digit code that is different from your confirmation number. Here is what it means and when you need it.

Delta Basic Business has the same lie-flat seat as Classic, but loses lounge access after Jan 2027 and earns fewer SkyMiles (MQDs are unaffected).

A Delta Medallion member can upgrade one companion for free — they just need a SkyMiles number and to clear at the higher-tier member’s window.

Delta Premium Select Basic has the same seat as Classic but loses seat selection, free changes, upgrades, and 3 fewer SkyMiles per dollar.

If Delta reroutes you onto another airline after a cancellation, your miles and MQDs don’t post automatically. Here’s how to request them back.

No — Air Canada (Star Alliance) and Delta (SkyTeam) share zero mileage earning. Delta’s actual Canadian partner is WestJet, not Air Canada.

United and JetBlue let you pool miles with family for free. Delta charges $0.01/mile plus a $30 fee for the same thing. Compare family pooling and points transfer rules, fees, and limits across every major US airline and hotel loyalty program.

Earn Medallion status faster: Delta Cars & Stays gives 1 MQD per $1 on hotel, vacation rental & car bookings. Book by Jul 20; travel by Dec 15.
