Planning a trip to the USA often starts with one difficult question: which part do you choose? New York has the landmarks, Florida brings sunshine and theme parks, Las Vegas offers something completely different, and the West Coast has cities, beaches and road-trip scenery.
As a FlightsPro travel agent, I often speak to people who do not want to choose just one. The good news is that they usually do not have to. In this USA multi-city trip guide, I explain how to make the holiday feel like one continuous journey, rather than four separate city breaks joined by rushed airport days. It covers the combinations I recommend, how long to spend in each place and how to avoid unnecessary backtracking.
Why the USA works so well for a multi-city holiday
The scale of the country looks complicated, but frequent domestic services and several useful gateways from the UK give travellers plenty of flexibility. That is one reason a carefully planned route can work far better than attempting to organise each destination separately.
An open-jaw itinerary is particularly effective. You might fly from London to New York, travel through the country and return from Los Angeles, rather than crossing America twice simply to catch the flight home. It saves time and can also reduce the cost of extra travel and hotel nights.
A multi-centre holiday also creates contrast. New York and Las Vegas could hardly feel more different; add relaxed days in Florida or California and the journey becomes much more varied. The purpose of this USA multi-city trip guide is to help you find that balance without trying to fit too much into one holiday.

Start your USA multi-city trip guide with a route, not a list of cities
One of the most common planning mistakes I see is choosing four dream destinations before checking how they connect. I prefer to build the journey in one geographical direction.
For travellers flying from the UK, that will often mean starting on the East Coast and finishing in the west:
UK → New York → Florida → Las Vegas → Los Angeles or San Francisco → UK
This route moves east to west and places the longer transatlantic flights at either end. You do not need every stop: for many people, three destinations create a better holiday than four.
Any useful USA multi-city trip guide should therefore begin with the route and available time—not simply a wish list of cities.
Three USA multi-city itinerary ideas
1. New York and Florida: 10 to 12 nights
This is one of the easiest first-time combinations in our USA multi-city trip guide. Spend three or four nights in New York, then fly south. Orlando suits theme parks and family holidays, while Miami works better for beaches and nightlife. With at least two weeks, you could include both.
Suggested split: 4 nights New York + 6 nights Orlando or Miami.
2. New York, Las Vegas and Los Angeles: 12 to 14 nights
If somebody asks me for the classic first-time route, this is usually my suggestion. New York delivers the big-city introduction, Las Vegas adds entertainment and desert scenery, and Los Angeles brings beaches and film culture. Direct flights link all three, although LA benefits from extra time because its attractions are spread out. It is also one of the most practical routes for travellers using a USA multi-city trip guide** to plan their first cross-country holiday.
Suggested split: 4 nights New York + 3 nights Las Vegas + 5 nights Los Angeles.
3. New York, Florida, Las Vegas and California: 16 to 18 nights
This is the full cross-country experience, but I would not squeeze it into two weeks. Four destinations mean three internal travel days. San Francisco can replace Los Angeles as the final stop, or extra nights can turn California into a two-city finish. If you want to include all four regions featured in this USA multi-city trip guide, allow enough time for each destination to feel worthwhile.
Suggested split: 3 nights New York + 5 nights Florida + 3 nights Las Vegas + 5 nights California.
Which cities combine best on a USA multi-city trip?
The best pairing depends on the type of holiday you want:
- New York + Orlando: a strong family route combining sightseeing with theme parks.
- New York + Miami: city energy followed by warmer weather and time near the beach.
- Las Vegas + Los Angeles: two contrasting cities connected by a short flight or a desert road trip.
- San Francisco + Los Angeles + Las Vegas: ideal for travellers who want a western route without crossing the whole country.
- New York + Las Vegas + San Francisco: a city-focused itinerary with excellent food, entertainment and very different neighbourhoods.
- Orlando + Miami + the Florida Keys: a good alternative for travellers who would rather explore one state in more depth.
Choose places for contrast rather than collecting city names. New York with nearby East Coast cities suits history and culture; adding Florida or California creates a broader mix. A good USA multi-city trip guide should help you choose destinations that complement one another, rather than simply increasing the number of stops.
When should you fly between cities?
Early flights can protect sightseeing time, but a 6am departure may mean leaving the hotel before 4am and losing the rest of the day to tiredness.
For most routes, I look for a departure between 8am and 11am. It usually gets you to the next hotel by mid-afternoon without a painful start. Late flights can work, but arriving in an unfamiliar city near midnight rarely improves a holiday.
Time zones matter too. New York is three hours ahead of Las Vegas and Los Angeles, so a westbound flight may appear shorter on the clock. Travelling east has the opposite effect and can consume much more of the day. This is another reason our USA multi-city trip guide generally recommends building UK itineraries from east to west.
How do multi-city and open-jaw fares work?
A multi-city booking allows different flight sectors to be searched together instead of forcing the journey into a standard return. For example, your international ticket could be:
- London → New York
- Los Angeles → London
The journey between New York and Los Angeles is then arranged separately through internal flights, rail or a road trip. This is commonly called an open-jaw fare because you arrive in one US city and return from another.
It is worth comparing two approaches: placing every flight on one itinerary, or booking the long-haul open-jaw fare and adding domestic flights separately. The lowest visible fare is not always the best overall option. Baggage charges, seat selection, airport transfers and inflexible ticket rules can quickly close the difference.
Separate tickets also need more care. If two independently booked flights connect on the same day and the first is delayed, the second airline may not be responsible for rebooking you. You may also have to collect and recheck your luggage. As this USA multi-city trip guide recommends, leave a generous buffer—or arrange an overnight stay—when separate tickets are unavoidable.
Practical details that can change the whole route
Check the airport, not only the city name. Several stops have multiple airports or terminals far from the main visitor areas. A cheap fare can lose its value once transfers are added.
Baggage is another important point. A checked bag may be included on the transatlantic sector but chargeable on a US domestic flight. Allowances can also differ between airlines, even when the flights appear in the same search result.
Finally, avoid adding a destination simply because the flight is short. Every change involves packing, checking out, travelling to the airport, passing through security, collecting baggage and checking into another hotel. When preparing a USA multi-city trip guide itinerary, I count each internal flight as at least half a travel day.
What is the best time for a USA multi-city trip?
There is no perfect month for every stop. Spring and autumn often suit city-heavy routes, while Florida is popular for winter sunshine. Las Vegas can be extremely hot in summer, and California’s coast differs considerably from inland areas.
Decide which part matters most. Families may prioritise Florida during school holidays, while a city and road-trip itinerary may suit milder spring or autumn weather. Major events and public holidays affect prices, so flexibility of even a few days can help.
The best time to follow this USA multi-city trip guide will therefore depend on your main destination, preferred weather and the experiences you consider essential.
How we plan USA multi-city trips at FlightsPro
When a customer gives me four cities and two weeks, I do not immediately start pricing hotels. At FlightsPro, we map the flights first. We compare arrival and departure gateways, test open-jaw fares and see whether changing the order could save money—or, just as importantly, save an entire travel day. We then plan the hotel stays around the actual flight times, allowing for airport transfers, baggage rules and check-in times.
A late arrival is never treated as a full sightseeing day simply to make the itinerary look better. You tell us the places you refuse to miss, the pace you enjoy and the budget you want to protect; we turn that wish list into one connected journey, with low-deposit options available to make booking easier.
Unlike a general USA multi-city trip guide, this personalised planning takes your exact dates, flight options, hotel preferences and available budget into account.
Let the journey breathe
My simplest advice is to leave something out. It sounds strange coming from someone who plans multi-city trips, but a good itinerary is not the one with the most pins on the map. It is the one where you still have time for an unplanned lunch, a slower morning or a day that does not begin in an airport.
For 10 nights, choose two destinations. For 12 to 14 nights, three stops usually work well. Save four destinations for a trip of at least 16 nights. That balance gives each place its own character instead of turning the holiday into a sequence of check-ins.
Use this USA multi-city trip guide as a starting point, then let FlightsPro build your multi-stop flights around the route as a whole. We can combine open-jaw international fares, domestic connections and realistic hotel-night splits. Tell us which American cities are on your list and how long you have; we will work out the order that makes the trip feel easy.
