Ticket prices are always reflected based on demand.
I flew last week on a trip I was supposed to take last June. (Not inernational, relax Covid travel police). The fare was $35 more than it was last year. I flew Delta and like advertised, many of the seats were blocked. But not all. There were a total of 4 flights. Three of those flights were full (full as in all the "available" seats were taken.) Service was a small ziploc bag with two small snack bags and a bottle of water. First class was also offered beer and wine. That's it. No other service. No hot beverages. No soft drinks. You could get more water if you wanted (8 oz bottles.) They did hand out disinfectant wipes when boarding and there was another one in the snack bag. On one flight FC was offered a larger snack box including hummus, cheese, crackers and a microscopic toblerone.
I have to fly the same route next week and the tickets were bought less than a week ago. The price is up 25% but much of that could be because of last minute ticketing. However, I have to fly the same route in a month and the same trip is now costing another 10% above the new amount. The airline must predict that demand will be higher especially as more and more people get vaccinated.
The airports were busy and most gates seemed pretty full. Of course, people were disancing so it may have just seemed more crowded as every other seat was empty.
Airlines have been losing money faster than ever before. They need to make it up. They will charge what the market will allow and what people will put up with. People will be traveling (and not just RS followers going to Europe.) Most people haven't traveled in over a year to see family, or take a vacation. They're ready and so are the airlines.
The same is true for the hotel. Next week I'm paying less than I did last week. But in a month, the hotel is almost sold out and all lower priced rooms are gone as well as all discounts. The hotel I am currently in now doing about twice as much business as it did six months ago.
Travel is picking up. And when the demand goes up, so do the prices.
