Which airline performs best in summer 2026?

Jet2 at a projected 82 percent on-time, Delta at 80 percent, Alaska at 79 percent. All three combine fleet reliability with weather-resilient networks.

Which airline performs worst in summer?

Frontier at 56 percent on-time, Spirit at 59 percent, JetBlue at 61 percent. ULCCs are hit hardest by afternoon thunderstorm cascades and tight aircraft rotations.

Does summer hurricane season affect my claim?

Hurricanes are extraordinary circumstances under EU261/UK261, exempting cash compensation. DOT refunds apply regardless of cause. Trip delay insurance also pays out.

Is summer claim volume higher than winter?

Yes at the US total-passenger level. Winter has higher per-day peak during storm events. Summer has sustained elevated claim volume June through August.

Should I book morning or evening flights in summer?

Morning. On-time rates drop 15 to 20 percentage points by late afternoon due to thunderstorm and crew cascade.

Are summer delays worse at hub airports?

Yes. ATL, ORD, EWR, SFO run near capacity all summer. Non-hub secondary airports (BWI, MDW, LGB) often perform better.

Does travel insurance cover hurricane cancellations?

Trip cancellation: yes if destination is under a hurricane warning. Trip interruption: yes if trip started. Trip delay: yes for 6+ hour delays regardless of cause.
