(1) As far as I know, airlines generally can't find connecting tickets. Please consult carefully when booking tickets. It is suggested that the transit should be as little as possible, and the pet consignment should be handled in domestic and foreign sections.
(2) When booking a ticket, please inform the airline that there are pets to be checked randomly, and ask whether the flight has an aerobic cabin and whether pets can be brought.
As far as I know, many airlines have restrictions on the temperature when handling pet consignment business. If the air temperature is higher than a few degrees, they will not handle the pet consignment. It is suggested that you estimate the temperature of travel time in advance, and try not to buy airline tickets with limited temperature to avoid the trouble of later consignment.
(3) When booking a ticket, most airlines will tell you that the pet aerobic cabin can only be booked 2 or 3 days before boarding. Most airlines require you to go to the counter to handle the pet aerobic cabin. Telephone consultation cannot be handled. Please apply as soon as possible before boarding.
(4) Some airline customers may not be familiar with the international pet consignment business, and may give wrong information during telephone consultation. It is recommended to go to the airline ticket counter for consultation and detailed confirmation.
