You land at Harry Reid International Airport (LAS) after a 10-11 hour direct flight from London. The next 30-90 minutes are what UK travellers ask about most in our WhatsApp: what CBP will ask, what to have ready, and how long the immigration queue actually takes on a Saturday night arrival.
The Harry Reid arrival - step by step
Direct London-Vegas flights (BA from LHR, Virgin Atlantic from LHR) land at Harry Reid International Airport (LAS) at Terminal 3, which handles all international arrivals. Terminals 1 and 2 handle domestic-only.
The sequence after landing: 1. Deplane and walk to CBP (Customs and Border Protection). Terminal 3 arrivals area, follow "International Arrivals" signage. 2. Split immigration lines: US Citizens / Green Card / Global Entry / Visitors. Everyone on ESTA queues in Visitors. 3. Wait for the officer. Typical wait 20-60 minutes off-peak. Fri-Sat 8pm-11pm arrivals and event weekends (F1, Super Bowl, NYE) can hit 90-120 minutes. 4. CBP interview. 30-90 seconds usually. Officer scans passport, takes fingerprints (all 10), takes facial biometric photo, asks 3-5 standard questions. 5. Admitted OR sent to secondary. If admitted, you get a paper stamp or (since 2023) digital-only entry with an I-94 record accessible online. If sent to secondary inspection, you wait in a separate room; total time can extend 60-120 minutes. 6. Baggage claim. Terminal 3 baggage carousels. Depending on flight, bags land 15-45 minutes after last passenger clears immigration. 7. Customs check on the way out. Green channel (nothing to declare) or Red channel (declaration required). Officers may spot-check green-channel passengers. 8. Exit into arrivals hall. LTV Sprinter transport meets you at the arrivals-hall pickup area (specific curb assigned per booking).
Total from wheels-down to sitting in your Sprinter: 60-120 minutes on a good day, 2-3 hours on peak event weekends.
What CBP will ask - the standard questions
The officer has a short script. Answers should be brief, factual, consistent with your itinerary, and match what's on your ESTA.
Standard questions (all UK arrivals get these): 1. Purpose of visit? Answer: "Tourism" or "Business" - pick one, don't hedge. "A bit of both" reads as evasive. 2. Length of stay? Answer: exact number of days, matching your return flight ("Seven days" not "about a week"). 3. Where are you staying? Answer: hotel name AND address ("Cosmopolitan, 3708 Las Vegas Boulevard South"). Have this in your phone before you land. 4. Return flight date and carrier? Answer: exact date + airline ("22 November, British Airways"). 5. How much money do you have with you? Answer: honest number in GBP or USD, INCLUDING what other members of your party have combined if travelling together. 6. Occupation? Answer: specific role ("Software engineer" not "IT", "Solicitor" not "Legal").
Follow-up questions if the officer probes: - What's your relationship to the group you're travelling with? - Have you been to the US before? When and for what? - Are you carrying any commercial merchandise or samples? - Do you have any US contacts you're visiting?
Answers that create problems: - "I'm not sure" (specifically about length of stay - looks like intent to overstay) - "It depends" (looks like flexible-ended trip) - Contradiction between ESTA statement and what you say (ESTA said tourism, you say "meeting some clients") - Nervous/evasive body language (this is subjective but officers are trained to read it)
What to declare at customs - and what to leave at home
The green/red channel decision at customs is straightforward. Green means "nothing to declare"; red means you have something that requires reporting. Undeclared items in the green channel can be seized and result in a fine.
Must declare (red channel or FinCEN 105 form): - Cash over US$10,000 (or equivalent GBP/EUR) combined for the party travelling together. Under $10,000 is fine to bring but not to declare. Over $10,000 requires FinCEN 105 form - not a fine, just a declaration. - Fresh fruit, vegetables, meat, dairy - even in sealed retail packaging. Fresh food is generally prohibited from import. UK snacks in original manufacturer-sealed packaging (biscuits, crisps, chocolate) are usually fine; if in doubt, declare. - Prescription medication in unusual quantity. Personal-use quantities (up to 90 days) in original pharmacy packaging with visible prescriber name are fine. Larger quantities need declaration. - Commercial goods for sale (samples, merchandise). - Firearms, ammunition, explosives (never bring). - Cuban cigars or rum brought commercially (personal-use quantities have been legal since 2016).
Leave at home: - Fresh fruit and veg (will be seized at agriculture check) - Meat products including sandwiches with meat/cheese fillings (fully prohibited) - Absinthe over the US 10mg/kg thujone threshold (though commercial brands sold in UK duty-free are usually within US limits) - Any product containing Kinder eggs (banned in the US due to choking hazard laws)
Fine to bring: - Personal jewellery and watches - Laptops, tablets, phones (though CBP can inspect device contents at their discretion) - Vitamins and non-prescription medication in reasonable quantity - Cosmetics and toiletries under 3.4oz (100ml) in a clear bag if in cabin - Sealed UK snacks and biscuits
Global Entry for UK citizens - is it worth it
Global Entry is a US CBP programme that lets vetted low-risk travellers skip the standard immigration queue and use a fast-track kiosk instead. UK citizens are eligible via the UK enrollment scheme.
Cost: - US$100 for the 5-year US CBP membership (about £77 currently) - Plus a UK Home Office background check fee (about £42 currently) - Total: approximately £120 for 5 years
Process: - Apply online at ttp.dhs.gov (US programme) and via the UK Home Office portal (paylater on gov.uk) - Attend a conditional-approval interview - can be done on arrival at a US port with a Global Entry office (LAS has one) or at Global Entry Enrolment on Arrival at select UK airports (LHR terminals 2, 3, 5) - Fingerprints + biometric photo at interview - 3-6 months wait for full approval typically
Once approved: - Skip the visitor immigration queue on every US arrival - Use the automated kiosk instead (scan passport, take photo, done in 30 seconds) - Saves 20-90 minutes per US arrival - Also gets you TSA PreCheck for US domestic flights (shorter security lines, keep shoes on, etc.)
Break-even math for UK travellers: - 4+ US trips over 5 years = worth it (£30/trip equivalent for time saved) - 2-3 trips over 5 years = borderline - 1 trip = not worth it
Global Entry works at LAS, LAX, JFK, MIA, ORD, SFO, IAH, DFW, ATL, SEA, BOS, MSP, PHL, IAD, DTW, PHX and every other major US port.
F1 week, Super Bowl, NYE - peak arrival planning
Immigration wait times at LAS on peak arrival weekends can hit 3 hours. If you're arriving during any of these windows, plan the day differently:
F1 Grand Prix week (mid-November): every direct London flight lands into peak immigration. Wed and Thu arrivals see 30-60 min waits; Fri/Sat arrivals see 90-180 min.
Super Bowl weekend (early February since Allegiant Stadium): Sunday arrival is worst; Fri/Sat still bad; Wed/Thu manageable.
Christmas Eve / NYE arrivals: 60-120 min sustained through the week.
Standard peak Sat evening (8-11pm): 45-75 min normal.
Planning around this: - Book flights that land Wed or Thu for those event weeks rather than Fri/Sat - Add a 2-3 hour buffer to any onward plans you have on arrival day - Do not book a Wed 8pm dinner reservation if your flight lands 5pm on F1 week - Global Entry pays for itself on any of these weekends alone
If your flight lands late and you have a Sprinter waiting, the driver monitors your flight in real-time - if immigration is running long, they park up and wait; no need to rush.
Questions
Frequently asked
- How long is the immigration queue at LAS airport when I land from London?
- Typically 20-60 minutes off-peak. Friday and Saturday 8pm-11pm arrivals run 45-75 minutes. Event weekends (F1 in November, Super Bowl in February, NYE) can hit 90-180 minutes. Global Entry members skip this queue entirely via automated kiosks.
- What questions will CBP ask at Las Vegas immigration?
- Standard: purpose of visit (tourism/business, pick one), length of stay (exact days), where you're staying (hotel name + address), return flight date and carrier, and occupation. Occasionally: how much cash you're carrying, whether you've been to the US before, relationship to travelling companions.
- Can I bring British food into the US when arriving at LAS?
- Sealed retail-packaged UK snacks (biscuits, crisps, chocolate) are usually fine. Fresh fruit, vegetables, meat, dairy - even in packaging - are generally prohibited. Kinder eggs are banned. If in doubt about a specific item, declare on the customs form; unlisted-and-detected items get confiscated with possible fine.
- How much cash can I bring into the US on arrival?
- Any amount is legal - up to $10,000 combined for people travelling together needs no declaration. Over $10,000 combined requires filing a FinCEN 105 currency declaration form on arrival. Undeclared amounts over $10,000 can be seized.
- Is Global Entry worth it for a UK citizen going to Vegas?
- Break-even is 4+ US trips over the 5-year membership. Total cost about £120 (US$100 CBP fee + UK Home Office fee). Saves 20-90 minutes per US arrival and gets you TSA PreCheck for US domestic flights too. For anyone doing an annual Vegas trip plus other US trips, yes.
- What happens if CBP sends me to secondary inspection at LAS?
- You wait in a separate room while an officer runs additional checks. Not usually a bad sign - often just a random secondary or a database question needing manual review. Typical wait 30-90 minutes. Bring a book. Do not take photos or use your phone in the secondary area (posted rule). Bring the officer whatever they ask for; be brief and factual.
