Is a 30 min layover in New York long enough?

LGA · La Guardia · New York, United States
Cutting It Close

No, 30 minutes is probably not enough for a layover at LGA (New York).

Too tight given LGA's re-screening requirement for any terminal change and walk times within larger terminals.

Tips for 30 min Connections
Check your terminal assignment carefully — a same-airline connection can still require a terminal change, especially between Delta's Terminal C and American/United flights in Terminal B.
If you must switch terminals, budget at least 45-60 minutes for the shuttle bus ride plus re-screening, more during peak traffic hours.
Delta-to-Delta connections within Terminal C are the easiest at LGA since gates are close together post-security.
Avoid tight connections through LGA during morning (7-9am) and evening (4-8pm) rush hours when both airport traffic and security lines peak.
If your connection involves the Marine Air Terminal (Delta Shuttle), allow extra time since it's a separate, older building slightly removed from the main terminal complex.

Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
There is no AirTrain or sterile inter-terminal walkway at LGA; the free Port Authority shuttle bus loops between terminals landside, typically taking 10-20 minutes depending on traffic and stops. Because the connection happens outside the secure zone, anyone changing terminals must go through security screening again, which is the single biggest time sink at this airport.
