You can see list of supported video formats, when open the drop-down list of file types near the bottom of the Insert Movie and Sound dialog box. I have no problem with playing video of different formats in my LibreOffice Impress. I suggest you install last codec pack, for instance K-Lite Codec Pack. edit delete.
The rules are the same for paid tickets. American Airlines Canceling an award ticket costs $150 for the first award, and $25 for each additional award reinstated at the same time for the same account. Thereâs no fee to change an award ticket, so long as the origin and destination remain the same.
Delta charges a fee of $150 to redeposit the miles into your frequent flyer account (waived for Diamond and Platinum Medallion members). To cancel your award ticket on Delta Air Lines, log into your SkyMiles account and enter your name and confirmation number and select the option to cancel. Alternately, go to My Delta > My Trips and locate your flights and select the option to cancel.
