The itinerary "Air Transport E-Ticket travel itinerary" is supervised by State Taxation Administration of The People's Republic of China and included in the invoice management of tax authorities. The official launch of the ticket in travel itinerary is the proof of payment and reimbursement for passengers purchasing domestic air transport e-tickets. For travel itinerary, it is not only a special invoice, but also a transport voucher, and it is also the preliminary evidence of the establishment of an air transport contract and registered securities (tickets).

The procedures for using e-ticket to fly are further simplified. You can get a boarding pass with the logo of "ET" as long as you show your valid identification at the airport check-in counter. Passengers don't need to show their air tickets any more. They only need to hold boarding passes marked with "ET" and valid identification, so they can conduct security checks.

Precautions for travel itinerary:

The simple way to identify whether there is a trap in the price is that the quotation of the travel agency should be 81% or 91% of the sum of the expenses paid by the tourists themselves, such as air tickets, accommodation, catering, tickets and transportation. Because travel agencies and airlines, hotels and scenic spots have team price concessions, the average discount range is 5~7 fold, and adding 1 ~ 31% profit on this basis is a reasonable quotation in the true sense.

Many travel agencies mostly use adjectives such as "value group", "pure play group", "popularity group" or "luxury group" to distinguish them. Generally speaking, the quality of the "value group" is relatively poor, but it is only reflected as "value" when quoting. Please polish your eyes.
