Horizon Air recommends that passengers be checked-in and at the boarding gate at least 30 minutes before the flight is scheduled to depart. The cut-off time for passengers flying domestically (with hand luggage only) is 30 minutes prior to departure. From Atlanta, Denver, Las Vegas, and Newark airports it's 45 minutes. The cut-off check-in time for travellers taking international flights is one hour.

Hand baggage: one carry-on bag is allowed, measuring 25 x 43 x 61 cm and a one personal item (purse, briefcase or laptop computer). Items bigger than this will be stowed in the hold; the charge is $25 per piece.

Checked: "Regular Travelers" pay $20 to check-in the first, second or third pieces of luggage. Elite Level Mileage Plan members or Delta Air Lines Medallion Diamond, Platinum, Gold, and Silver members or First Class passengers have a free checked-luggage allowance of two bags. Each bag should not exceed 22kg (50 lbs) in weight and 157cm (62in) in length.

Excess: a piece of luggage that weighs more than 22kg (50lbs) will be charged $50 in excess fees (one way). If the bag or suitcase exceeds 157cm (62in) the extra charge is $50 (160-203cm or 63-80in) one way. If the bag measures between 206-292cm (81-115in) the cost is $75 one way.

In Coach Class, the seat pitch is between 79 and 81cm (31 and 32in). First Class flyers enjoy a seat pitch of 91-94cm (36-37in).
