There is no extra charge for catering on the passenger plane, because it is already included in the fare. In many low-cost airlines, passengers have the right to choose plane meals: whether or not this happens, and if they choose to eat, of course, they have to pay extra.

There are three versions of catering provided on the plane:

1) According to the class of cabin: first class, business class, economy class. The quality and weight of catering vary greatly in different cabins, and you get what you pay for.

2) Flight time

less than 61 minutes: one snack, one cake and one carton drink. Less than 4 hours:

1. Frequent customers have a good chance to upgrade

Generally, airlines are economy class, then business class and then first class, which means upgrading the class. If you fly frequently, you must go to the airline website to become a member. When the ticket is oversold, you have a great chance to be upgraded, and sometimes the free ticket you exchange for membership points also has the opportunity to upgrade, that is, you don't have to spend money to sit in business class or even first class. I remember what happened to the uncle of Emirates when he was three years old.

2. Note the special time when buying the ticket

You can note it when buying the ticket when you happen to be near the special day. If you are going on a honeymoon, you can also inform in advance. In order to show humanistic care, airlines may often get small surprises, either free upgrades or small gifts.

3. Worry about your figure

When your size exceeds the seat and you can't stretch your width, or your long legs with nowhere to put them suffer from folding, you can tell the flight attendants about your worries and you may be upgraded if you have a seat. After all, there are real cases of this kind of thing.

4. Dress appropriately

Expensive luggage, handbags, sunglasses and watches may all be your passes to be upgraded. The same is true for a straight suit and a business person's dress. It will be much stronger if you get a good impression from the flight attendants in glamorous clothes. Let yourself look like you just finished reading the financial news in the VIP lounge, put on a smile and get on the plane.

5. Be kind to others and take the initiative to give up your seat

Don't hesitate to change your seat to a friend or couple who want to sit next to you. The flight attendants will also give you extra points for your upgrade trip. When the plane is late, being angry and cooperating may achieve the result of upgrading, but if you are angry, it may not be worth the loss, so ...... You know, after all, our purpose is to upgrade the cabin.

6. Arrive early in the off-season

Generally, there are one or two seats where you can upgrade, and the plane will actually be empty in the off-season, so you can try to arrive at the counter early. In order to balance the weight before and after the plane, you will consider upgrading some passengers, and if you arrive early, this opportunity may be yours!

7. If you arrive late in the peak season

, don't pre-select seats, and then arrive very late. In normal times, there are always some passengers who don't get on the plane in time or change their seats. At this time, the attendance rate will not be 111%. In order to ensure the attendance rate, there will be a situation where several people pre-select a seat. If you arrive late, another person may get a seat. At this time, the airline may upgrade you, because the economy class is full.
