01 / DECISION TRAPS

What can reverse the ranking?

The lowest headline fare remains provisional until these route-specific decision layers have been checked.

01
Codeshare price differences are easy to miss
Add the missing cost or protection difference to both offers before deciding.
02
Basic fares change the real total
Verify the exact operating carrier and ticket structure on the final checkout screen.
03
Early arrival utility varies by airport
Compare the schedule after a plausible delay, not only when every flight runs on time.

02 / AIRPORT-PAIR + CODESHARE PROFILE

Compare outcomes—not city labels.

This is a qualitative decision map, not a live schedule or fare table. Use it to normalize the candidates you find today.

01

JFK → LHR

Dense comparison set

Price the New York origin trip and Heathrow arrival separately.

02

EWR → LHR

Different ground journey

A lower fare can lose if Newark is materially harder to reach.

03

JFK / EWR → LGW

Arrival-cost alternative

Treat Gatwick transfer time and cost as part of the fare.
