Can I bring a scuba diving regulator in my carry-on?

Yes. Regulators are generally allowed in carry-on. However, the scuba tank itself must be completely empty with valve removed. Regulators without tanks are fine.

  • Regulators without tanks are standard personal items, allowed in carry-on and checked bags

  • Scuba tanks are prohibited unless completely empty with valve removed (open for inspection)

  • The tank interior must be open to inspection, security may require valve to be unscrewed

  • Tanks pressurized below 2 Bar are not restricted as hazardous materials but still require inspection

  • Place small regulator parts (o-rings, washers) in a zip lock bag to prevent loss

  • Bring spare o-rings for reassembling after security

You follow the signs, confirm your pickup point in the app, and wait for your driver there. Outside the US it gets more complicated. Some cities rest...

Can I get a refund for a missed bus?

Almost never. If you miss the bus, the ticket is forfeited unless you have a flexible or refundable fare. Standard bus ticket (Greyhound, Megabus, FlixBus): no refund for no-show Missed due to bus arriving early? Complaint possible but refund unlikely Rideflex or Fully Flexible fares: cost 2-3x standard, allow changes Best strategy: arrive 30-45 minutes early, track bus in app Travel insurance: rarely covers missed bus unless connecting from a delayed flight Traveling soon? See our Travel Essentials page. Want a deeper dive? ↓ Detailed Answer How It Works Missing a bus and getting a refund are two different things. Most standard tickets are non-refundable the moment the bus departs. The operator considers you a no-show and the seat is gone. This applies to Greyhound, Megabus, and FlixBus across virtually all standard fares. The exception is when the operator caused the miss. If the bus left early, never showed up, or broke down, you have a legitimate claim. The key i...

Can I use my phone charger internationally?

Yes, but you need a plug adapter (different outlet shape) and possibly a voltage converter if your device isn't dual voltage. Most phones, laptops, tablets: dual voltage (100-240V) - only need plug adapter Hair dryers, straighteners: often single voltage (110V) - need converter or burn out USB chargers: almost all dual voltage, just change the plug Adapter kit: $10-20 on Amazon works for 150+ countries As an Amazon Associate, I earn from qualifying purchases. Find this on Amazon: Universal travel adapter A Complete 2026 Guide The short answer is: almost certainly yes, but with one small catch. Most modern phone chargers are dual voltage, meaning they work from New York to New Delhi without a heavy power converter. What you actually need is a simple plug adapter - a tiny, cheap device that changes the shape of your plug to fit the wall outlet. However, there are important exceptions. Some older devices, hair tools, and cheap electronics are single voltage. Plug a 110V-only device i...
