Flight from San Diego to Boston

alyciaFlew with American Airlines-Mar 2026

Switching terminals in Boston was a VERY long walk -- dont cut your connection close if you are going from B to E

NicoleFlew with JetBlue-Apr 2026

Bring your own snacks/food. Extra legroom is nice but not really worth the extra money, unless you want free alcohol.

ericFlew with Air New Zealand-Jan 2025

At least two hour connection Buy food pre-flight
