Looks like United’s rolling out a MileagePlus debit card. Earns 1 mile per $1 on UA purchases and 1 mile per $2 on everything else plus some kind of earning on your balance, like AA’s Bask account.
Could be useful for places that charge fees for credit cards but not debit. Still, not sure why anyone would use it for United spend over a credit card. Curious if anyone here would actually go for it?
