Is a short international layover enough time to clear customs?

Non-citizens or travelers facing long immigration lines risk missing their connecting flights because standard itineraries do not account for these delays.

“I’m flying from Australia (Perth) to the US for the first time and I’m a little nervous about my connection at Dallas/Fort Worth.”source ↗
“I know wait times can vary massively, so I’m not expecting anyone to predict exactly what will happen. I’m mostly hoping to hear from people who have actually done a similar connection at DFW and learn what I should expect.”source ↗
“That’s plenty of time… assuming your first flight is on time. It won’t take much of a weather delay, etc. for your travel plans to completely unravel. I would never book two separate bookings so close together; I’d probably want an overnight in between.”source ↗
“Our main concern is booking the train in advance. Since our flight could be delayed and we’re not sure how much time we should allow to get from Alicante Airport to Alicante train station, we’re worried about missing the train and losing the money we paid for the tickets.”source ↗
“I booked through American’s website, so despite the second leg being operated by Iberia, that’s a single ticket - yeah?”source ↗
“When returning to the US from Heathrow, I have a layover in Dublin for 1.5 hours. Will I go through customs here or in Chicago??”source ↗
“Hi, looking at a flight from Europe that has a layover of 2 hours and 47 minutes at JFK in the afternoon.”source ↗
“I am a not a citizen so immigration takes longer than usual (+ there’s collecting and rechecking bags) but even then I have done international to domestic transfers at SEA and LAX in the past and they have never taken me more than 1.5 hours. Never done this at JFK before so some insight would be appreciated.”source ↗
“Do I need to exit the transfer section and re-enter through security check and passport check as I'm technically getting into a completely different flight or is it enough that I use the transfer section and go through the security check there?”source ↗
“I’m aware that I’m cutting it close, but I’m looking for HOW close….1h45m layover”source ↗
“Does 2 hours 40 minutes sound like enough time? I understand that it's pretty strict with passport controls and security etc in the UK after Brexit so I'm a bit worried.”source ↗
“Total time from landing to takeoff would be 2:20. What are the odds I make that transfer? Is this a good idea?”source ↗
“Note: I am a US citizen so not sure how HKG works and whether I'd have to clear customs again.”source ↗
“I'm looking at booking Vienna to Zurich then Zurich to DC with a 3hr 20min layover. Since I'm booking separate flights instead of together (so I can use miles) I assume I'll need to grab my bags and recheck them. Is this possible or would I be cutting it too close?”source ↗
