Do I need to leave the airport for self-transfer?

Do you have to go through security when transferring?

Nope, usually not. Unless you're transferring between airlines that are total opposites of each other, like Southwest and, I don't know, a private jet service. Then, buckle up, buttercup! You'll be doing the TSA tango twice. It's like going through a really slow, slightly humiliating, X-ray machine twice. Ugh.

Key things to remember:

• Domestic flights within the US? Generally, smooth sailing. One security check is enough to satisfy even the most suspicious TSA agent.
• International flights? That's a whole different kettle of fish. Prepare for another round of pat-downs and "Are you carrying any liquids?" questions. My Aunt Mildred got pulled aside for carrying a jar of pickles last year!
• Different airports, different rules. Some smaller airports are more lax, while bigger hubs like JFK are… well, JFK. You know what I mean.
• Connecting flights on the same airline, usually you’re good. It's like a magic trick. You vanish into one terminal and reappear in another. Poof!

Seriously though, check your specific flight details. Airlines and airports are as predictable as a toddler's tantrum. My brother-in-law spent an extra two hours at O'Hare because he didn't check this! Don't be like him! Avoid the pickle incident.

Do you have to go through security for an international layover?

Okay, security for international layovers... Hmmm. Always a pain, right?

Ugh, customs and immigration. Yep, gotta do that usually. First point of entry. Right. Does that mean I have to take out my liquids again?

• International layovers often mean security. Like, a re-screening. Fun.
• Domestic, nah, usually not. Unless...?
• Customs, immigration? Def for international connections. Every time I've flown, it's been a must! So annoying.

Wait, my trip to Rome last year! Did I do security in Amsterdam again after landing from Detroit? I did! I think I did. Argh! Why?

• Rome Trip 2024: Detroit -> Amsterdam -> Rome. Did security twice!
• Liquids rule, still a thing, right?
• Passport, check. Boarding pass, check. Sanity...questionable.

Why can't they just...know it's me? Global Entry. I need Global Entry. Global Entry is important!

Okay, so usually security. But maybe, sometimes, if you're lucky...no? Still, gotta plan for it, I guess. Better safe than sorry and miss that connecting flight.

Do I have to exit the airport for connecting a flight?

Connecting flights, eh? Usually, domestic-to-domestic connections don't require exiting security. Unless, of course, the airport architects had a really off day, and the terminals aren't internally connected. A logistical oops.

Now, a domestic-to-international hop? Surprisingly, often you can stay within security, even when switching terminals. Though admittedly less often. Makes sense, right?

Exceptions crop up. Consider large hub airports. Some designs necessitate exiting and a security rerun. Or it all depends on your airlines' fine print. Navigating airports can feel like interpreting ancient runes at times.

My aunt Marge got stuck at Denver last year. I think her connection was like…a nightmare, involved a shuttle bus. The horror. These things happen. Airports, sigh.

• Domestic-to-Domestic: Likely stay in secure area.
• Domestic-to-International: Possibly stay in secure area, but less likely.
• Terminal layout matters: Disconnected terminals necessitate re-entry to security.

Consider it a bit of airport roulette. You never quite know. I try to look at it like this. It’s all part of the journey.

Can you leave the airport if you have a connecting flight?

Yes, mostly. Leaving the airport during a layover is generally okay. Airlines sometimes even promote stopovers. But yeah, there are rules, obviously.

Caveats though. Always gotta be caveats, right? I wonder if my mom watered the plants. Need to check later.

• Visa requirements are important. Duh.
• Gotta make sure you have enough time to get back. Missed my flight to Tulsa once. Never again.
• The flight can't be domestic... usually. International connections are a different story. Passport control and all that.

Passport! Always check the expiry date. Mine's good until 2027, I think. Ugh, paperwork. Need to do taxes soon. Procrastination, my favorite hobby.
