Independent travel agency. Not affiliated with or endorsed by United Airlines, Lufthansa or any airline. Service subject to ticket control and airline rules.

Before requesting service: BookMyReservations is operated by Shiv Travel & Tours LLC. We can review eligible reservations where authorized; some tickets must be handled by the airline or original issuing provider. Airline fare differences and any applicable agency charges should be confirmed before proceeding.

Same-Day Change or Standby?

A confirmed same-day change and same-day standby are different requests. Eligibility and availability depend on the ticket, route, fare type and current airline policy.

Travel Day and Airport Constraints

Check whether the new flight departs on the eligible travel day and meets the airline’s airport and routing rules. Changes between nearby airports are not automatically permitted.

Premium Cabin Availability

A confirmed seat in United First or Polaris on the original flight does not guarantee the same cabin on an earlier or later service. Review the replacement cabin and fare rules before making a decision.

Connections and International Segments

Multi-leg and international journeys can require additional checks. A same-day change to one leg may disrupt minimum connection times or partner-operated flights.

Standby and Checked Bags

Standby acceptance is not a guaranteed seat. Baggage handling, check-in cutoffs and airport processing may limit practical options.

When to Contact the Airline

For airport-day operational decisions and standby priority, United may be the most direct source. Agency assistance is subject to ticket control and authorization.
