Scorecards

Why each product scored what it did

#1 · Best for business travel

Delta Air Lines

Delta ranks first on the measure that matters most to a working traveller: the flight leaves and arrives when it says it will. Award pricing is its weakest component.

#2 · Best for international itineraries

United Airlines

United's international route map is the strongest in the country, which is why it ranks second despite weaker consistency than Delta on domestic operations.

#3 · Best for domestic hub travel
