Hi!
Instead of looking for an agent, I can recommend that you look for a person who works for a wholesaler that deals in the particular area that you travel to most, as they will know the best deals/routes, and actually know the destination. Where as your typical travel agents has to try and know a little bit about the all the world. The only thing is that not manly wholesalers have a direct department of if they do its usually not advertised and is mainly via word of mouth/referrals only, as this is an avenue for clients who wish to book direct.
Wholesalers are companies that sell land and air to travel agents at a gross or nett price, and in some cases are the plug-ins suppliers for discount websites such as Expedia, Agoda etc.
I myself actually work for a wholesaler that specialises in Asia, and I do have a hand full of clients mainly family/friends of to which I sell airfares/land to at our wholesale sell point, so as a company we still make our wholesale margin, but avoids any “agent” commission we have to pay.
In most cases wholesale or private airfares need to be met with a minimum of 2-3 nights accommodation but this has never been audited that I know of, ticketing this type of airfare without the land is known as a dry airfare.
Prices? Well these are usually 5-7% cheaper for flights than the airlines websites and usually 9-13% cheaper than hotel websites/tour operators., how this works is that our wholesale margin for airfares are usually 13% where 5-7% are usually paid agent commissions and for land, wholesale margins are roughly 20-27%, where usually 9-13% are paid agent commissions. Agent commissions are different for all agents/chains/operators depending on the chain/preferred agreement etc,
Also not all wholesale fares are always cheaper, in some cases they are about the same price as published fares or ones that are on airlines websites, but offer more relaxed conditions, for example TTL/ticketing of a fare is not required until say 10/30/60 days prior to departure, it can also work the other way around where they are more restrictive, such as some don’t let you open jaw etc, and some are not event eligible for ff miles!
For example, flying to SYD/LHR RT in Business, anytime in Feb based on SQ D class, published and the SQ website have this coming in at $7664 + taxes, where I have just had a look at our fares/addendums it coming in at wholesale sell at $6820 + taxes, so I a saving of $844, however has restrictions such as add-one are not permitted so if you wanted to do a side trip with SQ add-on fares this would not be permitted.
Hope that helps
Inbox/pm me if you travel to Asia a lot in business!,
Cheers!
