Who needs travel insurance? Any traveler going anywhere in the world. That is, if they want to enjoy the trip and not worry about overseas medical care, getting home in the event of an emergency, or repairing their car (or someone else's) if there's an accident.

Many insurance companies offer travel coverage as part of their health insurance or other plans. But many companies offer travel insurance only, and they're basically the experts on anything and everything that can go wrong while you're halfway around the world.

But what insurance company should you choose to back up your travel plans? Here we'll look at the best-rated travel insurance companies in the United States (based on consumer feedback on sites like Consumer Affairs) and what scenarios they cover.

Generali Global Assistance

Consumers who have experience using Generali are quite satisfied with the service, according to Consumer Affairs. Generali covers things like Trip Cancellation, Travel Delay, Emergency Assistance & Transportation, and other services.

Individual plans from Generali range from Standard to Premium packages, with features like baggage loss covered up to $1,000 per person and $50,000 in medical and dental per traveler. You can pursue reimbursement for non-refundable travel expenses when emergencies occur, get help obtaining healthcare in foreign countries, and access extra cash if anything goes wrong while you're abroad.

Customers note that the purchasing experience is easy, figuring out coverage options is straightforward, and it's not hard to file claims and get follow-up help. Customer service is accessible and prompt, though you can just order your plan online without speaking to anyone if you so choose.

There's also a comprehensive FAQ page and online chat option to guide you through applying for coverage or filing a claim. You can get your policy and other docs mailed to you promptly, too.

Unlike other insurance companies, Generali covers pre-existing conditions, customers wrote, which made it possible for them to enjoy their trip and peace of mind. Pricing is also competitive, say reviewers, which makes Generali a no-brainer for your next trip.

Allianz Global Assistance

Travelers all over the web are big fans of Allianz. Their company has been around for over a century, and their nearly five-star average on Consumer Affairs proves they're a good company to go with. Oh, and industry giant AAA also endorses them as a travel partner, and that's enough qualifications for us. But Travel Weekly also awarded them "Best Insurance Provider" based on readers' feedback.

Allianz even offers no-receipts claim payments for certain scenarios. For example, they'll give you $100 per day for covered travel and baggage delays under one coverage option, even if you don't have proof via receipts. A mobile app makes claims and checking your policy even more accessible while on the go.

Allianz does have a ton of plans, which makes it tough to narrow down your options. At the same time, the extensive list means there's something for everyone! For example, OneTrip Prime covers a single trip, and kids 17 and under are included for free when traveling with a parent or grandparent.

There are other options like AllTrips Executive, an annual multi-trip plan that offers higher cancellation/interruption limits and even coverage for business equipment and rentals. You can get rental car damage protection, emergency medical per trip, and some options (like AllTrips Premier) include concierge service. The benefits on that plan extend to your entire household, too, and coverage lasts a year!

Customers love the prompt claims processing, online submission process, and helpful customer service professionals at Allianz.

Travelex Insurance Services

Travelex is another company that earns overall good reviews from consumers on Consumer Affairs. The insurance covers emergency medical coverage and evacuations, cancellations for business reasons, and handles trip interruptions and delays.

Your lost baggage is covered, Travelex can help you replace prescriptions and even travel documents, and there are upgrades available for certain, unique travel scenarios.

One huge perk for families is that kids 17 and under are covered under their parents' policies. As long as a covered adult is traveling with them, you won't be paying extra for individual coverage. Plus, three simple coverage options (Travel Select, Travel Basic, and Flight Insurance) make it easy to choose the services that are relevant to your situation and trip.

Their four-star (out of five) rating results from happy consumers who were thrilled to receive claims payments super fast. While there's a lot of paperwork involved when filing a claim (that's any type of insurance for you!), the turnaround tends to be quick. Plus, customers were able to get their disbursements through PayPal. That's an important note if you're abroad and waiting on an influx of cash to get treatment or get home.
