Fans set off in coaches at around 1.30am on the 520-mile round trip for Sunday's midday kick-off, only to witness a dismal display as Bournemouth shipped four goals at Huddersfield.
Howe — who is debating taking his squad abroad during the fortnight without a game — criticised Bournemouth's lack of desire.
"We were well aware of what sacrifices the fans made," he said. "I highlighted it to the players before the game.
"The time and money are extreme and their loyalty has been rewarded with a poor performance. I apologise to them for that.
"It's a difficult one to explain. We were below par, we were disappointing, we lost too many 50-50s. Collectively we weren't good today and individually we weren't good. The goals epitomised our performance really.
"We should look as hungry, if not hungrier, than them. Every game should be treated as a cup final.
"We're still in a relegation battle and we always have been. It's very tight and results like this don't help us."
