Two long-time industry executives told Reuters that Yellow's rates were roughly 10% to 20% below those of rivals. Loads in the so-called LTL market do not trade on the spot market and they vary based on the type and size of shipments, they said. "Yellow was way below" market rates, said Ken Adamo, chief of analytics at DAT Freight and Analytics, which operates one of North America's largest truck freight marketplaces. Unlike the highly fragmented trucking market, LTL is dominated by about a dozen players. Some providers are already raising rates, which could send LTL rates up 10% to 15% from current levels, Pickett said.
