It is possible to become a global travel agent or else receive a service through this site. The benefits are talking to a person who knows a fair amount about a country or locality. The disadvantage is that web-based travel agents might not know a great deal at the street level because they have never been to a spot themselves. This is why it pays to check out global travel reviews.
The first thing to know is that many places will eventually reopen to international travel. When they do, it is important to know what services and life is like in that area. This is where talking to call-in agents has its upsides and downsides. A company might have many agents who have niche expertise. This means that your query can be matched to a person who can make recommendations, being familiar with the locals.
The flip side is that an agent would have really had to have spent time in an area in order to grasp the local culture as well as the street food and available services. A web-based agent can actually find out a lot about a city and its inhabitants through the web, but it is not quite the same as someone with extensive local experience. A remote agent can be quite informative but only to an extent unless the person is a hired native.
A worker for a large travel agency might have access to a large database that offers a lot of deals as well as brochures for local businesses. Going through a larger company does usually mean a broader selection of possible deals. This could be great for a tourist who is not visiting anything other than commercial establishments, but it might not be so useful for someone who expects to spend a fair amount of time living in a local apartment and wandering the streets.
Getting a job as a travel agent means working remotely to talk to customers and then allowing the larger company to package deals to offer. This is separate from an independent agency where the agent has to solve a broader array of problems and do more paperwork. An independent agent or someone working for a brick and mortar firm is often better paid than a remote worker but has extra problems and liabilities.
