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
