Arriving at Seattle (SEA) FAQs
Cheapest economy fares typically include the lowest seat price with basic carry-on or seat selection restrictions, limited or no refunds, and change fees or high rebooking costs. These fares are excellent for price-sensitive travelers but verify baggage allowances and refund/change policies before booking.

Always check baggage policies and potential additional fees before confirming an ECO ticket.
