ето с някои добавки, може и без клас:

function solve(input, filterCriteria) {
  class Ticket {
    constructor(destination, price, status) {
      this.destination = destination;
      this.price = price;
      this.status = status;
    }
  }
  let tickets = [];
  input.forEach((line) => {
    [destination, price, status] = line.split("|");
    price = Number(price);
    tickets.push(new Ticket(destination, price, status));
  });
  let sorted;
  if (filterCriteria === "destination") {
    sorted = tickets.sort((curr, next) =>
      curr.destination.localeCompare(next.destination)
    );
  } else if (filterCriteria === "price") {
    sorted = tickets.sort((curr, next) => curr.price - next.price);
  } else {
    sorted = tickets.sort((curr, next) =>
      curr.status.localeCompare(next.status)
    );
  }
  return sorted;
}

без клас, с по-малко редове:

function tickets(arr, str){
    let tickets = arr.map(e=>{
            let [destination,price,status] = e.split("|");
            price = Number(price);
            return {destination, price, status};
        }).sort((a,b)=>{
            if(str==="price"){
                return 0;
            }else{
                return a[str].localeCompare(b[str]);
            }
        });
    return tickets;
