How to rebook your flight
There are a number of things you can do in terms of compensation and rebooking once your flight is canceled. While calling customer service, you should open the airline app to check what they are offering. Most will rebook you onto the next available service for no extra fee. However, if this doesn’t suit your travel plans then you should continue to hang on the phone line to talk to a customer service agent as soon as possible, preferably before all the other passengers realize this and do the same call as you. We know the wait times to get through to these guys can be huge, but most airlines will have both domestic and international customer service numbers. If you try the domestic line but the wait time is high, use the international numbers. Beware though, there may be additional charges from your mobile service provider.
Ground staff at the service center can sometimes, weirdly enough, have more authority than customer service on the phone such as the ability to put put you on waitlists or find seats the remote team does not see. So our recommendation is always go stand in line while calling customer service, and act fast because the best rebooking alternatives normally go fast and to priority customers.
How to get compensation
You are entitled to a full refund if your flight is canceled, but you could also get other forms of compensation such as meal vouchers and hotel stays. This varies from airline to airline so a quick Google will tell you what you may be covered for depending on who you were meant to be flying with.
