I suggest you consolidate all travel authorizations, orders and vouchers under DTS and shut down eFinance. Currently, some organizations refuse to issue travel orders through DTS when cross-org funding is required which causes the need for non-DTS travel vouchers. This is redundant and wasteful. We invested in DTS, now it's time to use it to recoup the investment and standardize travel procedures DoD-wide.
Potential gov't buyers should be allowed to purchase travel under the lowest airline bid, (DTS) and not just what GSA has provided. Some airlines offer lower priced airfare.
Allow DTS travelers to purchase a discount airline ticket for official travel, if they are willing to accpet the risks of travel being cancelled. For instance a ticket on Southwest will often be 50% less than the government ticket. If the trip is cancelled then Soutwest credits you the entire amount for future travel.
