For people who either are not rich or do not want to spend on tolls, dfw airport is the worst in world as there is no way to drive in to drop or pick up someone without paying toll. Even with a toll tag they charge $2 for first 30 minutes and $3 for first 2 hours. Considering all the issues with baggage, terminal construction even if you drive in after getting a call from someone who has landed, it usually takes more than 30 minutes. Chaching to DFW. It is even more confusing and degrading to visitors flying into DFW and renting. I will use and recommend Dallas Love field for this reason alone.
