How your total is worked out
Lean requirement ONE-5066 criteria5 proven1 open
WHEN an airline states a price with its parts THE SYSTEM SHALL total the price as its base amount plus its surcharges, fees, taxes and the consumption tax not included in it.
Lean: Rules.OneOrder.Offers.priceTotal
Your total starts from the fare, less any discount. We then add any surcharges, fees and taxes in the price. Any sales tax not already included is added on top. Every part of a price is in one currency, and a discount can never be larger than the fare it comes off.
How long a quoted price holds
Lean requirement ONE-5015 criteria4 proven1 open
WHILE no order has been created from an offer THE SYSTEM SHALL treat an offer item's price and inventory as guaranteed only until both the item's guarantee time limit and the offer's expiry.
Lean: Rules.OneOrder.Offers.guaranteesAt
A quote can come with a price guarantee that lasts until a stated time. Until then, we hold that price, as long as the offer itself is still open. The same goes for the seats in a quote that carries a seat guarantee. A guarantee never lasts past the time the offer closes. If a quote shows no guarantee time, its price is not guaranteed.
When you book
Lean requirement ONE-5026 criteria3 proven3 open
WHEN a customer accepts an offer whose items carry time limits THE SYSTEM SHALL create the order as ONE-001 does and give each order item its payment time limit and price guarantee from its offer item.
Lean: Rules.OneOrder.Offers.createOrder
When you accept an offer, your booking keeps the payment deadline and the price guarantee the offer showed. A deadline given as a length of time starts when your booking is made.
Choosing what to book
Lean requirement ONE-4014 criteria3 proven1 open
WHEN a seller selects items from an offer THE SYSTEM SHALL accept the selection only if it names items the offer holds and includes every item the offer marks mandatory.
Lean: Rules.OneOrder.Creation.selectItems
Some parts of an offer are optional, such as a bag or a seat. You can leave those out and pay only for what you keep. The parts an offer marks as required always come with it, and you can only book parts the offer contains.
Booking a whole trip at once
Lean requirement ONE-4025 criteria1 proven4 open
WHEN a seller sends a create request with selections from one or more offers THE SYSTEM SHALL check each selection and create one order from them, or reject the request.
Lean: Rules.OneOrder.Creation.createOrder
You can book flights from more than one offer in a single step. We check each part you chose and make one booking from them. A booking needs at least one item.
Still being decided
Booking several offers as one trip
Open criterion ONE-402.1open
WHEN a create request is accepted THE SYSTEM SHALL create one order item for each item selected from each offer and none for the items left out.
The sources allow one request to select from several offers and do not say what happens when one of them is rejected. …
Open theorem: Rules.OneOrder.Creation.create_items_match_selection
When you book from several offers at once and one of them can no longer be booked, we have not yet decided whether the rest goes ahead or the whole booking stops. If this happens to you, contact us before you pay and we will confirm what you hold.
A price after its guarantee ends
Open criterion ONE-502.4open
IF a customer accepts an offer after the price guarantee of one of its items has lapsed THEN THE SYSTEM SHALL not create the order at the offered price.
The guide recommends repricing into a new offer when a price guarantee has lapsed, and does not say what the airline must do when the customer accepts the offer before it expires. …
Open theorem: Rules.OneOrder.Offers.createOrder_price_guaranteed
A price guarantee can end before the offer closes. We have not yet decided whether you can still book at the quoted price in that window. If your guarantee has ended, contact us and we will confirm your price before you pay.
