Hot Tip: One of the best ways to detect with reasonable accuracy that you are on a codeshare flight is when the flight number format does not match similar flights on the same airline. In addition, many airlines also limit the question of whether or not you can update a codeshare flight, even if you have many miles from the exporting airline. As a general rule, low-cost airlines do not participate in Interline agreements, so be aware of this. Under this regulation, flights to the EU are only refundable (for example. B in case of delays of more than three hours) than if they are carried out by an EU airline. Over the past 30 years, consumers have often and rarely asked airlines to streamline and streamline the entire travel process. One of the by-products of consumer mood was code sharing. Under a codeshare agreement, the airline that manages the flight (the airline that holds the operating licenses, slots and flight planning/management and is responsible for ground-handling services) is often referred to as the CXR ope operator, although the term “carrier administration” of IATA SSIM is more specific. The reason is that a third party may be involved, usually in the event that the airline initially wishing to fly is forced to hire a subcontractor to operate the flight on its behalf (usually a wet ground lease, i.e. an aircraft is crewed and all flight facilities, usually due to capacity constraints, technical problems, etc.). In this case, the airline carrying the passenger should be designated as an operating airline, as it is the airline that carries passengers/goods. In most parts, you can`t update codeshare flights with miles on the marketing company.
For example, if you have booked a China Eastern ticket marketed by Japan Airlines, you cannot use Japan Airlines miles for an upgrade to China Eastern. If you want a chance to upgrade, you need to use the mileage of the running carrier. If you know that your flight is a codeshare flight, you should find out as soon as possible who the exporting airline is. If you fly in business class or first grade, you will undoubtedly find a different product than the one you booked at the beginning. To illustrate this concept, we say that you are booked on a business class ticket with a stop in Europe.
