## Prompt

You land at 1:35 PM with a connecting flight departing at 3:00 PM from the same airport. Clearing customs takes 25 minutes, the walk to your departure gate takes 15 minutes, and boarding closes 20 minutes before departure. Will you make the connection? Show your reasoning.

## Response

Yes — you make the connection with **25 minutes to spare**. Your required tasks finish at 2:15 PM, while the boarding cutoff is 2:40 PM.

## Timeline

| Step | Duration | Clock Time |
|---|---|---|
| Landing | — | 1:35 PM |
| Clear customs | 25 min | 2:00 PM |
| Walk to gate | 15 min | 2:15 PM |
| **Arrive at gate** | — | **2:15 PM** |
| Boarding closes (20 min before 3:00 PM) | — | 2:40 PM |

## The Math

Total transit time needed: \( 25 + 15 = 40 \) minutes.

Arrival at gate: \( 1{:}35 + 0{:}40 = 2{:}15 \) PM.

Deadline: \( 3{:}00 - 0{:}20 = 2{:}40 \) PM.

Buffer: \( 2{:}40 - 2{:}15 = 25 \) minutes.

## Caveats Worth Noting

The 25-minute cushion is comfortable but not bulletproof, because the problem ignores several real-world steps:

**Deplaning time** — Getting off the aircraft typically takes 10–20 minutes depending on your seat row, and that clock starts at 1:35 PM only if the plane reaches the gate on time.

**Baggage reclaim** — Many customs regimes require you to collect checked bags before clearing, then re-drop them. If that applies, add 20–30 minutes and the connection becomes tight or impossible.

**Security re-screening** — Connecting through customs often means passing back through a security checkpoint, which isn't accounted for in the 15-minute walk.

If all three apply, you would be arriving around 2:45–3:00 PM and would miss the cutoff. Under the numbers as stated, however, you're clear.

Would you like me to rework the timeline with deplaning and baggage re-check included to see how much slack actually remains?
