For carry-on, containers must be 3.4 oz or less and fit in quart-sized bag. For checked bags, total quantity per person cannot exceed 2 kg (70 oz) per person, and each container cannot exceed 0.5 kg (18 oz) .

  • Carry-on: 3.4 oz (100ml) limit per container, all fit in one quart-sized bag 

  • Checked bags: total aggregate quantity per person cannot exceed 2 kg (70 oz) or 2 L (68 fl oz), each container max 0.5 kg (18 oz) 

  • Aerosol release devices (button/nozzle) must be protected by caps to prevent accidental release 

  • Flammable or non-medicinal aerosols (paint, cooking spray) may have additional restrictions

  • The final decision rests with the TSA officer

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.

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.

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...

Can I use Uber at every airport?

No, Uber operates at most major airports but some (PDX, LGA certain terminals, some European airports) restrict ride-sharing to designated zones or ban them. US airports: almost all have Uber pickup zones (follow signs) Europe: allowed at major airports (LHR, CDG, FCO) but may cost more than taxis Japan: Uber only in Tokyo and a few cities, not at all airports Australia, Middle East: Uber available at major airports Traveling soon? See our Travel Essentials page. Want a deeper dive? ↓ Detailed Answer How It Works Uber is available at most major airports worldwide but availability and pickup rules vary significantly by location. In the US, nearly every large airport has a designated rideshare pickup zone. These are separate from taxi ranks and are usually signposted as "Rideshare" or "App-Based Rides." 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...
