"It sounds to me like I go in to, you know, get a ticket, my reasonable expectation is they're not going to charge me what they're going to charge, you know. I mean, it's unbelievable," Breyer said. Under Ginsberg's view of the case, Breyer said he could sue over the prices.
"That might be a great idea, but I don't think that's the idea behind this act," he said.
Ginsberg said in court papers that he and his wife flew almost exclusively on Northwest, logging roughly 75 flights a year to travel across the US and abroad to give lectures and take part in conferences on education and administration.
He said he flew on Northwest even when other airlines offered comparable or better flights and in 2005, reached the highest level of the WorldPerks program.
Northwest cut him off in 2008, shortly after Northwest and Delta agreed to merge. Ginsberg said the move was a cost-cutting measure designed to get rid of the high-mileage customers.
Northwest says Ginsberg complained 24 times in a 7-month period, including nine instances of luggage that turned up late on airport baggage carousels. Northwest said that before it took action, it awarded Ginsberg $1,925 in travel credit vouchers, 78,500 bonus miles, a voucher for his son and $491 in cash reimbursements.
The airline pointed to a provision of the mileage program's terms that gives Northwest the right to cancel members' accounts for abuse.
A decision is expected by late June.
