If you’re flying this week, here’s what you need to know about the storm and your options.The winter storm dubbed “Maya” by The Weather Channel — the NWS still feels it’s misleading to name winter storms — is expected to drop between 18 and 24 inches of snow in parts of the Northeast by Wednesday morning. Meanwhile, a new storm is plowing ashore on the Northwest coast. Snow totals are expected to surpass three feet in parts of Washington and Oregon through the end of the day Tuesday.Thankfully, you’ve got options if you’re traveling this week — even if you didn’t book the trip with a credit card that provides trip delay expense reimbursement from weather-related delays and cancellation.

After all, airlines don’t want you stuck sleeping on the airport floor either.Through 6:30am ET Monday, here are your options on Alaska, American, Delta, JetBlue, Southwest and United for flights Feb. 11 and onward.
