“Due to a technical error the e-ticket cannot be shown” error with Turkish Airlines. Anything I can do to view my reservation?

I’m trying to get into my Turkish Airlines reservation and I’m seeing the error on their website:

Due to a technical error the e-ticket cannot be shown.

If I try the mobile app, I’m seeing the error:

There has been a schedule change on your flight. Please contact our sales office or call center to confirm or to request a change and refund.

Is there a workaround that would let me see the latest status of my reservation, short of calling them? The current phone support waiting time is 27 minutes and in my experience the line often disconnects before you get a chance to speak to a human.

for online reservation system for airline which architecture is better,server-centric architecture or the client-centric architecture?

Case study: Online Reservation System for Air lines
The reservation system contains airline schedules, fare rates and tariffs as well as passenger and ticket reservation. The reservation system allows customers who use Orient Airlines to make reservations via the use of internet and mobile phone applications. The reservation system ensured effective customer service and in turn marketed and grew to become large airline with fleets of airlines in the region of hundreds and over 300 flights in a single day. By relying on their efficient reservation system, the airline was able to notice and see the importance of system upgrade as the systems for more processing power as the systems they relied upon were from the initial stages when the airline was relatively smaller and served fewer customers. The initial system also had limitations in linking prices and seat inventories to different airlines that worked with the Orient Airlines. Upgrading the system would allow to incorporate the feature of linking ability with the other airlines that cooperated with airline.
Three main actors of this system have been identified, these are
• Customers have basic permissions in the ticket booking system, can search the desired destination, choose a seat and make a payment in one click.
• Agents are users who can manage the functionality and have access to all features within the system.
• Administrator is able to manage every aspect of the system, has visibility to all features and changes system settings
a. Discuss with logical reasoning whether the server-centric architecture or the client-centric architecture will be more appropriate for this system?

magento2 – How to fix Magento 2 MSI inventory reservation inconsistencies directly via DB?

This query will return the reservation IDs from the reservations from every order that is either closed, complete or canceled, was created more than 2 weeks ago but has its reservation still different than 0 (which affects the salable quantity on the store, once their reservations were not properly finished).

SELECT to_be_deleted.reservation_id FROM (
    SELECT ir3.*, SUBSTRING_INDEX(SUBSTRING_INDEX(ir3.metadata, '_id":"', -1), '"', 1) AS order_id FROM inventory_reservation ir3
) to_be_deleted WHERE to_be_deleted.order_id IN (
    SELECT entity_id FROM sales_order WHERE entity_id IN (
        SELECT msi_info.order_id FROM (
            SELECT ir1.*, SUBSTRING_INDEX(SUBSTRING_INDEX(ir1.metadata, '_id":"', -1), '"', 1) AS order_id FROM inventory_reservation ir1
        ) msi_info WHERE msi_info.order_id IN (
            SELECT msi_info.order_id FROM (
                SELECT ir2.*, SUBSTRING_INDEX(SUBSTRING_INDEX(ir2.metadata, '_id":"', -1), '"', 1) AS order_id FROM inventory_reservation ir2
            ) msi_info GROUP BY msi_info.order_id HAVING sum(msi_info.quantity)<>0
        )
    ) AND created_at < NOW() - INTERVAL 2 WEEK 
);

You might be able to fix it by running this query.

DELETE FROM inventory_reservation WHERE reservation_id IN (
    SELECT to_be_deleted.reservation_id FROM (
        SELECT ir3.*, SUBSTRING_INDEX(SUBSTRING_INDEX(ir3.metadata, '_id":"', -1), '"', 1) AS order_id FROM inventory_reservation ir3

Any price comparison for car rental that send alerts when price drop at a certain amount set by user, without needing a reservation?

Do you know Any price comparison sites for car rental that send alerts when price drop at a certain amount set by user, so not just cents change or 5%, without needing a reservation to receive alerts?

Ideally would be to receive alerts for a destination when price per day, for a week long rental, reach X amount, without having to set the 100 alerts with different dates.

What ticket reservation do I need for a Schengen visa?

I have a visa appointment this Friday 19 at the Italian Consulate in Philadelphia and I have a question about the flight reservation requirement:
According to the Visa requirements “Confirmed flight reservation for a round trip showing complete itinerary.”

Does this mean I have to reserve the tickets, pay and print the itinerary?

In this case if my visa gets denied then I will lose the money I paid or can I just show the planned itinerary (written not booked)? in this case the travel agency would not give me the Travel Insurance coverage until I book and pay for the reservation.

I am a US green card holder and applying from North Carolina.

front end – Simple reservation system for a card game

I would like to set up a wordpress site for scheduling a four-player card game.
Assume each post is created to announce a card game with a date/time/location provided.
Assume each user is a registered subscriber.

I would like a simple way to click on a seat a the table and have that click reserve that person’s spot in the game. Ideally, anyone that looks at the post could see what seats are empty and which are taken. For the spots that are taken, I would like to see the username of the person that reserved the seat.

Finally, giving up a seat should be as simple as clicking on your username and the seat would go from reserved to empty. Also, clicking on a seat with someone else’s username on it would do nothing.

Any pointers on where to start? I have users and registration set up using the “simple membership” plugin. So, now what I really need is the frontend-editable chair. I am pretty lost on how to implement this feature.

"flight reservation" not specified Vs "flight reservation (round trip)" specified for European student & tourist visa

I am applying for student visa in France. They have among the documents: Flight reservation. How should I construe that, one way or round trip?

For Schengen tourist Visa, Flight reservation document is specified as round trip flight reservation.
